Chapter 8.22 EARTHQUAKE HAZARD REDUCTION IN EXISTING BUILDINGS Sections: 8.22.010 Purpose 8.22.015 Scope 8.22.020 Definitions 8.22.021 Rating Classifications 8.22.022 General Requirements 8.22.025 Administration 8.22.026 Analysis and Design 8.22.027 Materials and Construction 8.22.028 Information Required on Plans 8.22.010 Purpose. The purpose of this chapter is to promote public safety and welfare by reducing the risk of death or injury that may result from the effects of earthquakes on unreinforced masonry bearing wall buildings constructed prior to 1954 (the adoption date of the Building Code requiring earthquake resistant design of buildings) . Such buildings have been widely recognized for sustaining life-hazardous damage, including partial or complete collapse during moderate to strong earthquakes. The provisions of this chapter are intended as minimum standards for structural seismic resistance established primarily to reduce the risk of life loss or injury. Compliance with these standards will not necessarily prevent loss of life or injury or prevent earthquake damage to rehabilitated buildings. This chapter does not require alteration of existing electrical , plumbing, mechanical or fire safety systems unless they constitute a hazard to life or property. This chapter provides systematic procedures and standards for identification and classification of unreinforced masonry bearing wall buildings based on their present use. Priorities, time periods and standards are also established under which these buildings are required to be structurally analyzed and anchored. Where the analysis finds deficiencies, this chapter requires the building to be strengthened or demolished. - 14 - Qualified Historical Buildings shall comply with the State Historical Building Code (SHBC) established under Part 8, Title 24 of the California Administrative Code. 8.22.015 Scope. The provisions of this chapter shall apply to all buildings constructed or under construction prior to 1954 (adoption date of local earthquake resistant code requirements) , or for which a building permit was issued prior to 1954, which on the effective date of this ordinance have unreinforced masonry bearing walls as defined herein. EXCEPTION: This division shall not apply to detached one or two family dwellings and detached apartment houses containing less than 5 dwelling units and used solely for residential purposes. 8.22.020 Definitions.

An accurate record shall be kept of all such tests and of their locations in the building, and these results shall be submitted to the building official for approval as part of the structural analysis. 2. Number and Location of Tests. The minimum number of tests shall be two per wall or line of wall elements resisting a common force, or 1 per 1500 square feet of wall surface, with a minimum of eight tests in any case.

The bed joints of the outer wythe of the masonry shall be tested in shear by laterally displacing a single brick relative to the adjacent bricks in that wythe. The opposite head joint of the brick to be tested shall be removed and cleaned prior to testing. The minimum quality mortar in 80 percent of the shear tests shall not be less than the total of 30 psi plus the axial stress in the wall at the point of the test. The shear stress shall be based on the gross area of both bed joints and shall be that at which movement of the brick is first observed. 4. Core Tests. A minimum number of mortar test specimens equal to the number of required cores shall be prepared form the cores and tested as specified herein. The mortar joint of the outer wythe of the masonry core shall be tested in shear by placing the circular core section in a compression testing machine with the mortar bed joint rotated 15 degrees from the axis of the applied load. The mortar joint tested in shear shall have an average ultimate stress of 20 psi based on the gross area. The average shall be obtained from the total number of cores made. If test specimens cannot be made from cores taken, then the shear value shall be reported as zero. (f) Testing of Shear Bolts. One-fourth of all new shear bolts and dowels embedded in unreinforced masonry walls shall be tested by a Special Inspector using a torque calibrated wrench to the following minimum torques: 1/2" diameter bolts or dowels = 40 foot-lbs. 5/8" diameter bolts or dowels = 50 foot-lbs. 3/4" diameter bolts or dowels = 60 foot-lbs.

The test apparatus shall be supported on the masonry wall at a minimum distance of the wall thickness from the anchor tested. The rod anchor shall be given a preload of 300 lbs. prior to establishing a datum for recording elongation. The tension test load reported shall be recorded at one-eighth inch relative movement of the anchor and the adjacent masonry surface. Results of all tests shall be reported. The report shall include the test results as related to the wall thickness and joist orientation. The allowable resistance value of the existing anchors shall be 40 percent of the average of those tested anchors having the same wall thickness and joist orientation.
