1613.5.2 Wood Diaphragms.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code, renumbered from Sections 16 13.5.4 to match the new code format. This amendment is a revision to Section 12.11.2.2.3 of ASCE 7-10 reference document.

A joint Structural Engineers Association of Southern California (SEAOSC), Los Angeles County and Los Angeles City Task Force investigated the performance of concrete and masonry construction with flexible wood diaphragm failures after the Northridge earthquake. It was concluded at that time that continuous ties are needed at specified spacing to control cross grain tension in the interior of the diaphragm.

Additionally, there was a need to limit subdiaphragm allowable shear loads to control combined orthogonal stresses within the diaphragm. Recognizing the importance and need to continue the recommendation made by the task force while taking into consideration the improve performances and standards for diaphragm construction today, this proposal increases the continuous tie spacing limit to 40 ft in lieu of 25 ft and to use 75% of the allowable code diaphragm shear to determine the depth of the sub- diaphragm in lieu of the 300 plf and is deemed appropriate and acceptable. Due to the frequency of this type of failure during the past significant earthquakes, various jurisdictions within the Los Angeles region have taken this additional step to prevent roof or floor diaphragms from pulling away from concrete or masonry walls.

1613.5.3 Structural Separation.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code, renumbered from Sections 16 13.5.2 to match the new code format. This amendment is a revision to Section 12.12.3 equation 12.12-1 of ASCE 7-10 reference document.

The inclusion of the importance factor in this equation has the unintended consequence of reducing the minimum seismic separation distance for important facilities such as hospitals, schools, police and fire stations from adjoining structures. The proposal to omit the importance factor from Equation 12.12-1 will ensure that a safe seismic separation distance is provided.

This amendment is the same as in the 1999, 2002, 200$, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code, renumbered from Section 1617 to match the new code format. This amendment establishes design parameters to mitigate the increased seismic forces which are imparted upon structures located on sloping surfaces.

Due to the difficulty of fire suppression vehicles accessing winding and narrow hillside properties and the probabilities for future earthquakes in the Los Angeles region, this technical amendment is required to address the special needs for buildings constructed on hillside locations. A joint Structural Engineers Association of Southern California (SEAOSC) and both the Los Angeles County and Los Angeles City Task Force investigated the performance ofhillside building failures after the Northridge earthquake. Numerous hillside failures resulted in loss of life and millions of dollars in damage. These criteria were developed to minimize the damage to these structures and have been in use by both the City and County of Los Angeles for several years with much success.

1705.3 Concrete construction.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code.

This amendment requires special inspection for concrete with a compressive strength over 2500 psi as our code currently requires. Results from studies after the 1994 Northridge Earthquake indicated that significant damage was attributed to a lack of quality control during construction resulting in poor performance of the building or structure. Therefore, the proposed amendment requires special inspection for concrete with a compressive strength greater than 2,500 pounds per square inch. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. (Justification: Geologic and Topographic — See justification B and D in the attached matrix) Section IA — 57.
1705.12 Special inspections for seismic resistance.

This amendment is similar to the 2011, 2014, 2017 and 2020 Glendale Building and Safety Code, renumbered from Section 1705. 11 to match the new code format.

This amendment modifies an exception to require special inspections to detached one-or-two family dwellings located in Seismic Design Category D, E or F.

In southern California. very few detached one- or two-family dwellings not exceeding two stories above grade plane are built as “box-type” structures, especially those in hillside areas. Many steel moment frames or braced frames and/or cantilevered columns within buildings can still be shown as “regular” structures by calculations. With the higher seismic demand placed on buildings and structures in this region, the language in Sections 1705.12 Item 3 of the California Building Code would pennit many detached one- or two-family dwellings not exceeding two stories above grade plane with complex structural elements to be constructed without the benefit of special inspections. By requiring special inspections, the quality of major structural elements and connections that affect the vertical and lateral load resisting systems of the structure will greatly be increased.

1805.4.3 Drainage discharge.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code. This amendment requires site drainage devices, for all concentrated water, to be installed to the satisfaction of the building official and city engineer. This amendment will reduce damage and help prevent injury by requiring that drainage systems be installed to minimum standards established by the building official and the city engineer, thereby providing better control of the effect of concentrated drainage on property.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code. This amendment prohibits the use of spread wood footings. No substantiating data has been provided to show that wood foundation systems are effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effects of constant moisture in the soil and wood-destroying organisms. Wood foundation systems not properly treated and protected against deterioration, have performed very poorly and have led to slope failures.

This amendment clarifies additional reinforcing for stepped footing assigned to higher Seismic Design Category. With the higher seismic demand placed on buildings and structures in this region, precautionary steps are proposed to reduce or eliminate potential problems that may result for under reinforced footings located on sloped surfaces.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code, renumbered from Section 1 805.4.2. This amendment restricts the use of plain concrete in foundations supporting light frame construction. No substantiating data has been provided to show that under-reinforced footings are effective in resisting seismic loads and may potentially lead to a higher risk of failure. Therefore, this proposed amendment requires minimum reinforcement in continuous footings to address the problem of poor perforniance of plain or under-reinforced footings during a seismic event.

With the higher seismic demand placed on buildings and structures in this region, precautionary steps are proposed to reduce or eliminate potential problems that may result by following prescriptive design provisions for footing that does not take into consideration the surrounding environment. It was important that the benefit and expertise of a registered design professional be obtained to properly analyze the structure and take these issues into consideration. This amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Task Force that investigated the poor performance observed in the 1994 Northridge Earthquake.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code, renumbered from Section 2304.9.1 to match the new code format.

This amendment prohibits the use of staples as fasteners to resist or transfer seismic forces and shall not be permitted without being substantiated by cyclic testing. Due to the high geologic activities in the Southern California area and the expected higher level of performance on buildings and structures, this proposed local amendment limit the use of staple fasteners in resisting or transferring seismic forces. In September 2007, limited cyclic testing data was provided to the ICC Los Angeles Chapter Structural Code Committee showing that stapled wood structural shear panels do not exhibit the same behavior as the nailed wood structural shear panels. The test results of the stapled wood structural shear panels appeared much lower in strength and drift than the nailed wood structural shear panel test results.

Therefore, the use of staples as fasteners to resist or transfer seismic forces shall not be permitted without being substantiated by cyclic testing.

2306.2 Wood-frame diaphragms.

This amendment is the same as in the 2008, 2011. 2014, 2017 and 2020 Glendale Building and Safety Code.

This ai-nendment disallows the use of higher allowable (horizontal) diaphragm shear stress based on numerical calculation and requires the use of unit shear strength values as specified by the Code. The Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the damages to buildings and structures during the 1994 Northridge Earthquake recommended reducing allowable shear values in wood structural panel shear walls or diaphragms that are not substantiated by cyclic testing. That recommendation was consistent with a report to the Governor from the Seismic Safety Commission of the State of California recommending that code requirements be ‘more thoroughly substantiated with testing.” The allowable shear values for wood structural panel shear walls or diaphragms fastened with staples are based on monotonic testing and does not take into consideration that earthquake forces load shear wall or diaphragm in a repeating and fully reversible manner.

In September 2007, limited cyclic testing was conducted by a private engineering firm to determine if wood structural panels fastened with staples would exhibit the same behavior as the wood structural panels fastened with common nails. The test result revealed that wood structural panel fastened with staples appeared to be much lower in strength and stiffness than wood structural panels fastened with common nails. It was recommended that the use of staples as fasteners for wood structural panel shear walls or diaphragms not be permitted to resist seismic forces in structures assigned to Seismic Design Category D. E and F unless it can be substantiated by cyclic testing.
furthermore, the cities and county within the Los Angeles region has taken extra measures to maintain the structural integrity ofthe framing of shear walls and diaphragms designed for high levels of seismic forces by requiring wood sheathing be applied directly over the framing members and prohibiting the use of panels placed over gypsum sheathing. This proposed amendment is intended to prevent the undesirable performance of nails when gypsum board softens due to cyclic earthquake displacements and the nail ultimately does not have any engagement in a solid material within the thickness of the gypsum board.

This amendment is the same as in the 2002, 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code.

This amendment disallows the use of higher allowable diaphragm shear stress based on numerical calculation and requires the use of unit shear strength values as specified by the Code. This amendment also limits the minimum thickness of wood structural panel sheathing and establishes minimum nail spacing requirements. This amendment is necessary because unit shear strength values specified in the Code are based on actual cyclic tests, thereby providing a more reliable design strength. Furthermore, review of actual damage caused by recent earthquakes has revealed that diaphragms sheathed with thinner wood structural panels performed poorly and may have contributed to increased structural damage.

This amendment is the same as in the 2014, 2017 and 2020 Glendale Building and Safety Code to address a design deficiency not addressed in the base code, renumbered from Section 2309.3.1 to match the new code format.

During the Northridge Earthquake. 3/8” thick, 3 ply-plywood shear walls experienced many failures. Box nails were observed to cause massive and multiple failures of the typical 3/8” thick 3-ply plywood during the Northridge Earthquake. This proposed amendment specifies minimum sheathing thickness, nail size and spacing so as to provide a uniform standard of construction for designers and buildings to follow.

This is intended to improve the performance level of buildings and structures that are subject to the higher seismic demands and reduce and limit potential damages to property. This proposed amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake.

R503.3 Particleboard.

This amendment is the same as in the 2011, 2014, 2017 and 2020 Glendale Building and Safety Code.

This amendment makes the Residential Standards in Volume lB of the 2020 Glendale Building and Safety Code consistent with the Building Standards in Volume IA of the 2020 Glendale Building and Safety Code. This amendment prohibits the use of particle board diaphragms. This amendment is necessary because the severe lateral ground displacement that is frequently experienced throughout the local region results in very strong lateral forces on buildings. Investigations after the Northridge earthquake revealed that this material performed poorly as a lateral force-resisting element.

TABLE R602.3(1) FASTENING SCHEDULE.

This amendment is the same as in the 2011, 2014, 2017 and 2020 Glendale Building and Safety Code.

R602.3.2 Top plate.

This amendment is the same as in the 2011, 2014, 2017 and 2020 Glendale Building and Safety Code.

This amendment eliminates the use of single top plate construction to maintain the structural integrity of the framing of shear wall systems for building and structures subject to high seismic loads.

The performance of modern-day braced wall panel construction is directly related to an adequate load path extending from the roofdiaphragm to the foundation system. A single top plate is likely to be over nailed due to the nailing requirements at a rafter, stud, top plate splice, and braced wall panel edge in a single location.

In addition, notching on a single top plate for plumbing, ventilation and electrical wiring may reduce the load transfer capacity of the plate without proper detailing. Majority of buildings and structures designed and built per the California Residential Code with a single top plate may not need structural observation and special inspections. The potential construction mistakes mentioned above could not be caught and corrected by knowledgeable engineers and inspectors and could jeopardize structural performance of buildings and structures located in high seismic areas.

Section VI-15.
307.4.3 Portable outdoor fireplaces.

This amendment is the same as in the 2020 Glendale Building and Safety Code. This amendment adds restrictions related to the use of portable outdoor fireplaces when used in conjunction with one- and two- family dwellings located within a wildiand-urban interface fire area. Glendale is located in a region that has a seasonally dry climate, which often experiences strong Santa Ana wind conditions. The additional restrictions require a minimum separation of 15 feet between the portable outdoor fire place and any structure, combustible material or vegetation, to address the increased fire hazards that are associated with seasonal high-wind conditions which increase the risk of open-flame devices in the wildland-urban interface fire areas. The wildland-urban interface fire areas are located in areas of the city where steep, hillside topography increase the difficulty in addressing wind-driven fire events. (Justification: Climatic)
Section VI-16.
307.4.4 “Red-flag” and other high fire risk conditions.

This amendment is essentially the same as in the 2020 Glendale Building and Safety Code with some minor editorial updates. This amendment adds restrictions on open burning activities, including recreational fires and fires within portable outdoor fireplaces, on “red-flag” days or other days which pose a high fire risk. Glendale is located in a region that has a seasonally dry climate, which often experiences strong Santa Ana wind conditions. The additional restrictions reduce the risk of wind-driven fires that could occur on “red-flag” days that result from a combination of dry conditions and strong winds that frequently occur as a result of Glendale’s seasonal climate. (Justification: Climatic)
Section VI-17.
308.1.5 Location near combustibles.

This amendment is the same as in the 2020 Glendale Building and Safety Code. This amendment expands restrictions on open flame sources located in wildiand-urban interface fire areas and located within 10 feet of combustible construction or vegetation. Glendale is located in a region that has a seasonally dry climate, which often experiences strong Santa Ana wind conditions. The additional restrictions reduce the risk of unintentional fire ignition of combustible construction and/or vegetation, which would pose an extreme safety risk due to the dry and windy climate. (Justification: Climatic)
Section VI-18.
308.1.9 Outdoor fires.

This amendment was part of Section VI-40 in Chapter 49 of the 2020 Glendale Building and Safety Code but is being relocated to Chapter 3. This amendment provides for restrictions on outdoor fires located in the wildland-urban interface fire areas, or High Fire Hazard Areas. Glendale is located in a region that has a seasonally dry climate, which often experiences strong Santa Ana wind conditions. The additional restrictions reduce the risk of unintentional fire ignition of combustible construction and/or vegetation, which would pose an extreme safety risk due to the dry and windy climate. (Justification: Climatic)

901.11 Critical equipment
This amendment is the same as the 2020 Glendale Building and Safety Code. This amendment defines “critical equipment”, and then establishes criteria for its location, ventilation, signage, and graphics.

Geologically, the City of Glendale is exposed to a high degree of seismicity that increases the likelihood of structural damage within buildings. Placement of critical equipment above the first floor of a building increases the likelihood that such equipment will be inaccessible for proper use after an earthquake.

Furthermore. earthquake-induced fires are more likely to occur in regions of high seismicity. and proper ventilation of critical equipment is necessary to maintain a tenable environment where such critical equipment must be accessed during an earthquake-induced fire. (Justification: Geologic)
Section VI — 27.
903.2.21 Where required
This amendment is the same as the 2020 Glendale Building and Safety Code reflecting Glendale’s fire sprinkler ordinance for both new and existing buildings originally adopted in 1989. Geologically, the City of Glendale is exposed to a high degree of seisrnicity that increases the likelihood of earthquake-induced fires. Climatically, seasonal Santa Ana wind conditions have the potential to exacerbate fire conditions, thereby placing a higher degree of reliance upon automatic fire sprinkler systems to assist in the early abatement of structure fires. Topographically, portions of Glendale are located within hillside areas that are accessible by steep, narrow and winding streets, which can delay the arrival of fire suppression resources; automatic fire sprinkler systems can provide early suppression until fire suppression resources can arrive on scene. All of these conditions contribute to the need for increased fire sprinkler standards.

This amendment also includes administrative procedures for notification and enforcement. (Justification: Administrative. Geologic, Climatic, Topographic) Section VI— 27.
906.8 Cabinets
This amendment is the same as the 2020 Glendale Building and Safety Code. This amendment establishes administrative standards for the placement of fire extinguisher cabinets, to ensure that fire extinguishers are located in cabinets to ensure location control of fire extinguishers. The height provision contained in the amendment is intended to coordinate with disabled access provisions to ensure fire extinguishers are accessible to individuals with physical disabilities. This amendment is administrative and does not affect any building standards.

Appendix B, Table B105.2, Required fire flow for buildings other than one- and two-family dwellings, group R-3 and R-4 buildings and townhouses
This amendment is the same as the 2020 Glendale Building and Safety. This amendment revises the model code’s reduction of fire flow from 75% to no more than 50% for buildings other than one- and two- family dwellings. Geologically, the City of Glendale is exposed to a high degree of seismicity that increases the likelihood of earthquake-induced damage to municipal water supply lines. Additionally, large magnitude seismic events often result in loss of power at water distribution pump stations, thereby interfering with water pressure throughout the city. The proposed amendment requires a greater fire flow requirement for buildings other than one- and two-family dwellings, thereby increasing the likelihood of adequate water supply to fight fires after a major seismic event that compromises the municipal water supply.

Section VI— 38.

Appendix C, Table C102.1, Required number and spacing of fire hydrants This amendment is the same as the 2020 Glendale Building and Safety Code which establishes fire hydrant spacing requirements. with some minor editorial clarifications.

Geologically, the City of Glendale is exposed to a high degree of seismicity that increases the likelihood of earthquake induced damage to municipal water supply lines. Additionally, large magnitude seismic events often result in loss of power at water distribution pump stations, thereby interfering with water pressure throughout the city. The proposed amendment requires a closer spacing of fire hydrants, thereby resulting in better access to water to fight fires after the municipal water supply is compromised after an earthquake.

extensive history of slope failures causing serious floods and mud slides especially when a heavy rainy season occurs after a severe brush fire. New constructions or additions in said areas must be regulated to assure that hillside slides will not be exacerbated, and if possible, will be improved.

E. This amendment is necessary for administrative clarification, which does not modify a California Building Standard pursuant to California Health and Safety Code Sections 17958, 17958.5 and 17958.7. This amendment establishes administrative standards for the effective enforcement of grading standards throughout the City of Glendale.

F. This amendment is justified on the basis of a local geologic condition. The City of Glendale is subject to earthquake hazards caused by its location on the Sierra Madre fault near the base of the San Gabriel Mountains. Said fault is the eastward extension of the same fault upon which the 1971 San Fernando earthquake originated. Other faults which potentially could cause seismic activity in the City include the Verdugo fault located near the southwest edge of the Verdugo Mountains and its branches to the east, the Sycamore Canyon fault, the Scholl Canyon fault and the Eagle Rock and San Rafael faults. The York Boulevard fault is also important in that it is a western extension of the Raymond Hill fault for which there is considerable evidence for recent geologic activity.

Said faults are generally considered major Southern California earthquake faults which may experience rupture at any time. This amendment establishes grading standards that are intended to improve the performance of graded sites that may be subjected to seismic movement, including both vertical and lateral ground surface acceleration. Thus, because the City is within a seismic area which includes earthquake faults within and through the jurisdictional limits of the City, the modifications and changes cited herein are necessary to better limit personal injury and property damage as a result of seismic activity and to establish criteria for repair of damaged property following a local emergency.

G. This amendment is justified on the basis of a local climatic condition. The seasonal climatic conditions during the late summer and fall create severe fire hazards as hot, dry weather in combination with Santa Ana winds frequently result in wildland fires in the thousands of acres of brush-covered slopes in the Verdugo and San Rafael Hills, Chevy Chase Hills and Repetto Hills areas of the city, which can rapidly denude natural vegetation. The City of Glendale is also subjected to heavy seasonal rains, which are generally more intense than most regions in California. The City’s orientation within the Verdugo Mountains results in a concentration of rainfall during the fall and winter seasons, which often result in severe ground and slope saturation. The City is situated on the alluvial flood plains of the Arroyo Verdugo Wash, Sycamore, Verdugo and Scholl Canyons and the Verdugo and San Gabriel Mountain drainages which have an extensive history of slope failures causing serious floods and mud slides especially when a heavy rainy season occurs after a severe brush fire. New construction and additions in said areas must be regulated to assure that hillside slides will not be exacerbated, and if possible, will be improved.
