AISC Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-05) are available on the AISC website for free.
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 )
