Section 7-5-196: REPAIRS. Section 3403 is amended as follows: For the purposes of this <br />chapter, the following repair requirements are hereby added as a new Subsection 3403.6 to the <br />San Leandro Building Code: <br />3403.6.1 Repairs. Repairs of structural elements shall comply with this section. <br />3403.6.1.1 Seismic evaluation and design. Seismic evaluation and design of an existing <br />building and its components shall be based on the following criteria. <br />3403.6.1.1.1 Evaluation and design procedures. The seismic evaluation and design shall be <br />based on the procedures specified in the building code, ASCE 31 Seismic Evaluation of Existing <br />Buildings (for evaluation only) or ASCE 41 Seismic Rehabilitation of Existing Buildings. The <br />procedures contained in Appendix A of the International Existing Building Code shall be <br />permitted to be used as specified in Section 3403.6.1.1.3. <br />3403.6.1.1.2 CBC level seismic forces. When seismic forces are required to meet the building <br />code level, they shall be one of the following: <br />100 percent of the values in the building code. The R factor used for analysis in <br />accordance with Chapter 16 of the building code shall be the R factor specified for <br />structural systems classified as "Ordinary" unless it can be demonstrated that the <br />structural system satisfies the proportioning and detailing requirements for systems <br />classified as "Intermediate" or "Special". <br />2. Forces corresponding to BSE-1 and BSE-2 Earthquake Hazard Levels defined in ASCE <br />41. Where ASCE 41 is used, the corresponding performance levels shall be those shown <br />in Table 3403.6.1.1.2. <br />TABLE 3403.6.1.1.2 <br />ASCE 41 and ASCE 31 PERFORMANCE LEVELS <br /> PERFORMANCE LEVEL PERFORMANCE LEVEL <br />OCCUPANCY FOR USE WITH ASCE 31 FOR <br />CATEGORY AND WITH ASCE 41 USE WITH ASCE 41 BSE-2 <br />(BASED ON IBC BSE-1 EARTHQUAKE EARTHQUAKE HAZARD <br />TABLE 1604.5 HAZARD LEVEL LEVEL <br />I Life Safety (LS) Collapse Prevention (CP) <br />II Life Safety (LS) Collapse Prevention (CP) <br />III Note (a) Note (a) <br />IV Immediate Occupancy (IO) Life Safety (LS) <br />a. Performance Levels for Occupancy Category III shall be taken as halfway between the <br />performance levels specified for Occupancy Category II and Occupancy Category N. <br />3403.6.1.1.3 Reduced CBC level seismic forces. When seismic forces are permitted to meet <br />reduced building code levels, they shall be one of the following: <br />ORDINANCE NO. 2007-022 26 <br />
