PREFACE

The AISC Load and Resistance Factor Design (LRFD) Specification for Structural
Steel Buildings is intended t oo o o o office cover the c mm n design criteria in r utine
practice. Acc rdingly, it is n t feasible t o o o also c ver the many special and unique
o f structural design practice. This AISC problems enc untered within the full range
Seismic Provisions for Structural Steel Buildings is a separate d cument that addresses
one such t pic: the design and c nstructi n o o o of structural steel and c mp site structural
steel/reinf rced c ncrete building systems in seismic regi ns. These Pr visi ns are
in three parts: Part I is intended f r the design and c nstructi n o o o of structural steel
buildings; Part II is intended f r the design and c nstruction of comp site structural
steel/reinf rced c ncrete buildings; Part III is an all wable stress design alternative
too the LRFD pr visi ns f r structural steel buildings in Part I. Additi nally, a list of
symbols, a Gl ssary, and a n n-mandat ry C mmentary with backgr und inf rmation
are pr vided. The first letter(s) o of w rds or terms that appear in the gl ssary are
generally capitalized thr ugh ut these Pr visi ns.

TheAISCC mmittee on Specificati n, Task C mmittee 113—Seismic Pr visi ns is
responsible f r ng ing devel pment f these Pr visi ns. Additi nally, the AISC C mmittee on
Specificati n has enhanced these Pr visi ns thr ugh careful scrutiny, discussion, suggestion
of r impr vements, and end rsement. AISC further ackn wledges the
vari us c ntributi ns o o o of several gr upsoting Seismic Safety C uncil (BSSC), the Nati nal Science F undati n (NSF), the SAC
