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 Moment 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.

Supplement No. 1 to Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications (ANSI/AISC 358-05s1-09)
This supplement to the 2005 standard, Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications, modifies an existing prequalified moment connection and adds three new prequalified moment connections. The principal additions contained in the supplement may be summarized as follows:

      • Bolted unstiffened extended end plate (BUEEP) moment connections and bolted stiffened extended end plate (BSEEP) moment connections have been prequalified for SMFs with concrete structural slabs, subject to the requirements of Chapter 6.
      • Bolted flange plate (BFP) moment connections are prequalified per Chapter 7.
      • Welded unreinforced flange-welded web (WUF-W) moment connections are prequalified per Chapter 8.
      • Kaiser bolted bracket (KBB) moment connections are prequalified per Chapter 9. (925 kB, 68 pages)

 

Patent Holder Statement
The Preface of ASNI/AISC 358-05s1 discusses the possibility that implementation of this standard may require use of subject matter covered by patent rights. More specifically, this refers to the use of the Kaiser bolted bracket (KBB) moment connection, for which the patent holder has filed this statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license.
