Structures or portions of structures that comply with the requirements of the applicable chapter <br />in Appendix A of the International Existing Building Code as specified in Items 2.1 through 2.5 <br />below shall be deemed to comply with this section. <br />2.1. The seismic evaluation and design of unreinforced masonry bearing wall buildings in <br />Occupancy Category I or II are permitted to be based on the procedures specified in Appendix <br />Chapter A1. <br />2.2. Seismic evaluation and design of the wall anchorage system in reinforced concrete and <br />reinforced masonry wall buildings with flexible diaphragms in Occupancy Category I or II are <br />permitted to be based on the procedures specified in Appendix Chapter A2. <br />2.3. Seismic evaluation and design of cripple walls and sill plate anchorage in residential <br />buildings of light-frame wood construction in Occupancy Category I or II are permitted to be based <br />on the procedures specified in Appendix Chapter A3. <br />2.4. Seismic evaluation and design of soft, weak, or open-front wall conditions in multiunit <br />residential buildings of wood construction in Occupancy Category I or II are permitted to be based <br />on the procedures specified in Appendix Chapter A4. <br /> 2.5. Seismic evaluation and design of concrete buildings in all Occupancy Categories are <br />permitted to be based on the procedures specified in Appendix Chapter A5. <br />3. Compliance with ASCE 31 based on the applicable performance level as shown in Table <br />404.2.4.2. It shall be permitted to use the BSE-1 earthquake hazard level as defined in ASCE 41 <br />and subject to the limitations in item 4 below. <br />4. Compliance with ASCE 41 using the BSE-1 Earthquake Hazard Level defined in ASCE 41 <br />and the performance level as shown in Table 404.2.4.2. The design spectral response <br />acceleration parameters Sxs and Sx1 specified in ASCE 41shall not be taken less than 75 <br />percent of the respective design spectral response acceleration parameters SDS and SD1 <br />defined by the California Building Code and its reference standards. <br />TABLE 404.2.4.2- Please see attachment B <br />PERFORMANCE CRITERIA FOR REDUCED CBC LEVEL SEISMIC FORCES <br />404.3.1 Referenced Standards <br />Standard Referenced <br />Reference In Code <br />Number Title Section Number <br /> <br />ASCE 31-03 Seismic Evaluation of Existing Buildings 404.2.4.1, <br />TABLE 404.2.4.1 <br />404.2.4.2, <br />TABLE 404.2.4.2 <br /> <br />ASCE 41-06Seismic Rehabilitation of Existing Buildings 404.2.4.1, <br />Including Supplement No. 1 TABLE 404.2.4.1 <br />404.2.4.2, <br />TABLE 404.2.4.2 <br />404.3.1 Lateral force-resisting elements are hereby deleted. <br />Page 2 City of San Leandro Printed on 11/15/2016
