Part I, Sec. 1. of the AISC Seismic Provisions is <br />revised as follows: <br /> <br />1. SCOPE <br />These provisions are intended for the design and <br />construction of structural steel members and connections in <br />the Seismic Force Resisting Systems in buildings for which <br />the design forces resulting from earthquake motions have <br />been determined on the basis of various levels of energy <br />dissipation in the inelastic range of response. These <br />provisions shall apply to buildings in Seismic Zone 2 with <br />an importance factor I greater than one, in Seismic Zone 3 <br />and 4 or when required by the Engineer of Record. <br />These provisions shall be applied in conjunction with, <br />Chapter 22, Division II, hereinafter referred to as the LRFD <br />Specification. All members and connections in the Lateral <br />Force Resisting System shall have a design strength as <br />provided in the LRFD Specification to resist load <br />combinations 12-1 through 12-6 (in Chapter 16) and shall <br />meet the requirements in these provisions. <br />Part I includes a Glossary, which is specifically applicable <br />to this Part, and Appendix S. <br /> <br />2. Part I, Sec. 4.1., first paragraph of the AISC Seismic <br />Provisions is revised as follows: <br /> <br />4.1 Loads and Load Combinations <br /> <br />The loads and load combinations shall be those in Section <br />1612.2 except as modified throughout these provisions. <br /> <br />38 <br /> <br /> <br />
