20.08.058 Division V - SEISMIC PROVISIONS FOR STRUCTURAL STEEL BUILDINGS <br />FOR USE WITH ALLOWABLE STRESS DESINGN -amended <br /> <br />Division V - SEISMIC PROVISIONS FOR STRUCTURAL STELL BUILDINGS FOR USE <br />WITH ALLOWABLE STRESS DESINGN of the California Building Standards Code 1998 <br />Edition, (24 C.C.R.), and including by reference the Uniform Building Code 1997 Edition, Parts <br />1, 2 and 3 is amended to read as follows: <br /> <br />Section 2212. Amendments. The AISC-Seismic provisions adopted by this Division apply to the <br />seismic design of structural steel members except as modified by this section. <br /> <br />A. The following terms that appear in AISC Seismic shall be taken as being identical to those <br /> shown in the 1997 Uniform Building Code: <br /> <br /> AISC-Seismic 1997 Uniform Building Code <br /> Seismic Force Resisting System Lateral Force Resisting System <br /> Design Earthquake Design Basis Ground Motion <br /> Load Combinations 4-1 and 4-1 Chapter 16 Eq. 12-17 and 12-8 <br /> respectively <br /> LRFD Specification Section A4-1 Chapter 16 Eq. 12-1 through 12-6 <br /> through A4-6 respectively <br /> f2oQE <br /> <br /> B. Part I, Sections 1 and 4.1 of the AISC-Seismic provisions are modified as follows: <br /> <br /> Part I, Section 1 is changed to read as follows: <br /> <br /> 1. SCOPE. These provisions are intended for the design and construction of structural steel <br /> members and connections in the Lateral Force Resisting Systems in buildings for which the <br /> design forces resulting from earthquake motions have been determined on the basis of various <br /> levels of energy dissipation in the inelastic range of response. These provisions shall apply to <br /> buildings in Seismic Zone 2 with an importance factor I greater than one, and in Seismic Zone 3 <br /> and 4 or when required by the Engineer of Record. <br /> <br /> These provisions shall be applied in conjunction with Chapter 22 Division II, hereinafter referred <br /> to as the LRFD Specification. All members and connections in the Lateral Force Resisting <br /> System shall have a design strength as provided in the LRFD Specification to resist load <br /> combinations 12-1 through 12-6 (in Chapter 16) and shall meet the requirements in these <br /> provisions. <br /> <br /> Use of an intermediate moment resisting steel frame is prohibited in Seismic zone 4. <br /> 36 <br /> <br /> <br />
