20.08.057 <br />plaster, gypsum veneer base, gypsum <br />sheathing boazd, and gypsum wall- <br />boazd shall not be used as vertical or <br />horizontal diaphragms in Seismic <br />Zone 4 where the near fault factor <br />exceeds 1.0. Exceptions may be <br />granted by the Director of Building <br />Inspection. <br />(Balance of section to remain) <br />(Ord. 1778 § 2, 1999; Ord. 1669 § 2, <br />1995) <br />Structural Steel Buildings For Use With <br />Allowable Stress Design of the Califor- <br />nia Building Standards Code 1998 <br />Edition (24 CCR), and including by <br />reference the Uniform Building Code, <br />1997 Edition, parts 1, 2 and 3 is <br />amended to read as follows: <br />Section 2212. Amendments. The <br />AISC-Seismic provisions adopted by <br />this Division apply to the seismic <br />design of structural steel members <br />except as modified by this section. <br />20.08.058 Division V -Seismic <br />Provisions For Structural <br />Steel Buildings For Use <br />With Allowable Stress <br />Design -Amended: <br />Division V -Seismic Provisions For <br />AISC-Seismic <br />Seismic Force Resisting System <br />Design Earthquake <br />Load Combinations 4-1 and 4-2 <br />LRFD Specification Section A4-1 <br />through A4-6 <br />~oQE <br />A. The following terms that appeaz <br />in AISC-Seismic shall be taken as <br />being identical to those shown in the <br />1997 Uniform Building Code: <br />1997 Uniform Building Code <br />Lateral Force Resisting System <br />Design Basis Ground Motion <br />Chapter 16 Equation 12-17 and 12-8 <br />respectively <br />Chapter 16 Equation 12-1 through 12-6 <br />respectively <br />Em <br />B. Part I, Section 1 and 4.1 of the <br />AISC-Seismic provisions are modified <br />as follows: <br />Part I, Section 1 is changed to read as <br />follows: <br />1. SCOPE. These provisions aze <br />intended for the design and construc- <br />tion of structural steel members and <br />connections in the Lateral Force <br />Resisting Systems in buildings for <br />which the design forces resulting <br />from earthquake motions have been <br />determined on the basis of vazious <br />levels of energy dissipation in the <br />inelastic range of response. These <br />provisions shall apply to buildings in <br />Seismic Zone 2 with an importance <br />factor I greater than one, and in <br />Seismic Zone 3 and 4 or when re- <br />quired by the Engineer of Record. <br />(Pleasanton April 2000) ']00_22 <br />
