This paper is the result of a multi-year effort to rewrite Chapter 16 of the ASCE/SEI 7-10 Standard, which is entitled Seismic Response-History Procedure. This paper documents the newly-proposed Chapter 16 requirements, as well as the rationale and logic behind the requirements. The goals of this paper are to: (a) explain the rationale for the newly proposed requirements, for those interested in why changes are being proposed; and (b) provide detailed explanation of the new requirements, to help future users properly apply the requirements in the design of new buildings. This effort was initiated by the Building Seismic Safety Council (BSSC) Provisions Update Committee (PUC) who formed an Issue Team with the specific mandate of proposing a fully rewritten version of Chapter 16. This newly proposed Chapter 16 will become a part of the 2014 National Earthquake Hazard Reduction Program (NEHRP) Provisions and then will be considered for inclusion in the ASCE/SEI 7-16 Standard.
