Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-05)
This ANSI-approved specification is a companion to the Specification for Structural Steel Buildings (ANSI/AISC 360-05) that extends coverage to the connection detailing and member design requirements for structural steel and composite structural steel and reinforced concrete systems in high-seismic applications. This new standard, dated March 9, 2005, replaces and updates the 2002 Seismic Provisions for Structural Steel Buildings as well as incorporating provisions for two new systems: buckling-restrained braced frames and special plate shear walls. Supplement No. 1, dated November 16, 2005, is incorporated into the new seismic provisions which affects only the section on ordinary concentrically braced frames (OCBF). (5.2MB, 330 pages )

Prequalified Connections for Special and Intermediate Steel Moments Frames for Seismic Applications (ANSI/AISC 358-05)
This standard has been developed by the AISC Connection Prequalification Review Panel in accordance with Appendix P of the Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-05). The connections have been prequalified for use in special and intermediate steel moment frames, without the need for additional testing. The standard currently addresses three types of connections - the reduced beam section (RBS) connection, the bolted unstiffened extended end plate (BUEP) connection, and the bolted stiffened extended end plate (BSEP) connection.

Recommended Seismic Design Criteria for New Steel Moment-Frame Buildings (FEMA 350)
This resource document provides recommended guidelines for the design and construction of steel moment frame buildings and alternative performance-based design criteria. It supplements the NEHRP Recommended Provisions for Seismic Regulations for New Buildings and other Structures. A series of pre-qualified connection details, as well as a detailed procedure for performance evaluation, is included. This document is located on a FEMA server. (2.4MB, 224 pages)
