8、l Steel Buildings, July 12, 2016American Institute of Steel Construction9.1-iiiPREFACE(This Preface is not a part of ANSI/AISC 341-16, Seismic Provisions for Structural Steel Buildings, but is included for informational purposes only.)AISC 360, Specification for Structural Steel Buildings (ANSI/AISC
9、 360-16) is intended to cover common design criteria. Accordingly, it is not feasible for it to also cover all of the special and unique problems encountered within the full range of structural design prac-tice. This document, Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-16) (her
10、eafter referred to as the Provisions), is a separate consensus standard that addresses one such topic: the design and construction of structural steel and composite structural steel/reinforced concrete building systems specifically detailed for seismic resistance.The Symbols, Glossary, and Abbreviat
11、ions are all considered part of this document. Accompanying the Provisions is a nonmandatory Commentary with background infor-mation and nonmandatory user notes interspersed throughout to provide guidance on the specific application of the document.A number of significant technical modifications hav
12、e also been made since the 2010 edi-tion of the Provisions, including the following: Inclusion of ASTM A1085/A1085M material New provisions for diaphragms, chords and collectors, particularly horizontal truss diaphragms Inclusion of Ryin Table D1.1 for more accurate slenderness limits and to avoid u
13、se of lower Fyvalues for dual-certified material Requirement that simultaneous inelasticity be considered for columns partici-pating in two or more seismic force resisting systems Clearer provisions on required strength of column splices and bases, including a reduced shear for column bases, returni
14、ng the requirements to closer to those in the 2005 Provisions Allowance for non-full strength connections in special moment frames Option to use partial-joint-penetration groove welds in moment-frame column splices Revised and clarified continuity plate, doubler plate, and associated welding provisi
15、ons Multi-tiered braced frame provisions for ordinary concentrically braced frames, special concentrically braced frames, and buckling-restrained braced frames Numerous revisions to special plate shear wall requirements New application of composite plate shear wall system using concrete-filled steel
16、 panel walls Power-actuated fasteners permitted in the protected zone up to a certain diameter New criteria to prequalify connections for composite moment framesAISC_SP SPEC 341_01_FM.indd 3 2/22/17 2:23 PMSeismic Provisions for Structural Steel Buildings, July 12, 2016American Institute of Steel Co

The AISC Committee on Specifications gives final approval of the document through an ANSI-accredited balloting process, and has enhanced these Provisions th
18、rough careful scrutiny, discussion and suggestions for improvement. The contributions of these two groups, comprising well more than 80 struc-tural engineers with experience from throughout the structural steel industry, is gratefully acknowledged. AISC further acknowledges the significant contribut
