scope:

These Provisions are intended for the design and construction of structural steel members and connections in the Seismic Load Resisting Systems in buildings for which the design forces resulting from earthquake motions have been determined on the basis of various levels of energy dissipation in the inelastic range of response. These Provisions shall apply to buildings that are classified in the Applicable Building Code as Seismic Design Category D (or equivalent) and higher or when required by the Engineer of Record.

These Provisions shall be applied in conjunction with the AISC Load and Resistance Factor Design Specification for Structural Steel Buildings, hereinafter referred to as the LRFD Specification. All members and connections in the Seismic Load Resisting System shall have a Design Strength as required in the LRFD Specification, and shall also meet all of the additional requirements in these Provisions.

Part I includes a Glossary, which is specifically applicable to this Part, and Appendices P, S, and X.
