DEDICATION

Professor Egor Popov

This edition of the AISC Seismic Provisions is dedicated to the memory of Professor Egor Popov. Professor Popov was a Professor for over 50 years at the University of California atBerkeley, and a long time member of the AISC Committee on Specifications. Professor Popov focused a major portion of his career improving the understanding and seismic performance of steel structures. He was instrumental in the development of seismic design provisions for steel structures for over thirty years, and initiated the activity of AISC in this regard in the late 1980’s. As Chair of TC113(the predecessor of TC9), he led the publication of the first two editions of the AISC Seismic Provisions. Until the time of his death at the age of 88 early in 2001, Professor Popov remained a very active member of TC9 in the role of Vice Chair. His contributions to the development of these provisions and understanding of the seismic performance of steel buildings is unequaled, and will long beremembered and appreciated by AISC, the steel industry and the structural engineering profession. It is entirely fitting that these provisions be dedicated to the memory of Professor Egor Popov.

PREFACE

(This Preface is not a part of ANSI/AISC 341–02, Seismic Provisions for Structural Steel Buildings, but is included for information purposes only.) The AISC Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings is intended to cover the common design criteria in routine office practice. Accordingly, it is not feasible for it to also...
