S Occupancies, the pr/mary use shall be limited to storage, <br />factories or workshops. Minor accessory uses shall be <br />allowed in accordance with the provisions of Section 302. <br />Structures on which this exception is used shall not have <br />equipment attached to the structural frame or shall have <br />such equipment detailed to accommodate the additional <br />drift. Walls that are laterally supported by the steel frame <br />shall be designed to accommodate the drift in accordance <br />with Section 1633.2.4. <br /> <br />Section 20.08.117 Section 1630.10.3 - amended - Limitations <br /> <br />Section 1630.10.3 of the California Building Standards Code 2001 Edition <br /> (24 C.C.R.), and including by reference the Uniform Building <br /> Code, is amended to read as follows: <br /> <br />1630.10.3 Limitations. The design lateral forces used to <br />determine the calculated drift may disregard the limitations <br />of Formula (30-6) and (30-7) and may be based on the <br />period determined from Formula (30-10) neglecting the 30 <br />or 40 percent limitations of Section 1630.2.2, Item 2. <br /> <br />Section 20.08.119 Section 1633.2.4 - amended - Deformation <br /> <br />compatibility <br /> <br />Section 1633.2.4 of the California Building Standards Code 2001 Edition <br /> (24 C.C.R.), and including by reference the Uniform Building <br /> Code, is amended to read as follows: <br /> <br />1633.2.4 Deformation compatibility. All structural <br />framing elements and their connections, not required by <br />design to be part of the lateral-force-resisting system, shall <br />be designed and/or detailed to be adequate to maintain <br />support of design dead plus live loads when subjected to <br />the expected deformations caused by seismic forces, pA <br />effects on such elcnnents shall be considered. Expected <br />deformations shall be determined as the greater of the <br />Maximum Inelastic Response Displacement, <br />considering Pzl effects determined in accordance with <br />Section 1630.9.2 or the deformation induced by a story drift <br />of 0.0025 times the story height. When computing expected <br />deformations, the stiffening effect of those elements not <br />part of the lateral-force-resisting sys-tem shall be neglected. <br /> <br />44 <br /> <br /> <br />
