New SEI/ASCE Disproportionate Collapse Mitigation Standard
Donald O. Dusenberry
Abstract
For the past several years, a committee of the Structural Engineering Institute of the American Society of Civil Engineers (SEI/ASCE) has been drafting a new standard addressing analyses and design for the mitigation of disproportionate collapse of buildings and other structures. It strives to be a performance standard, providing guidance for analyses, acceptance criteria, quantification of anticipated collapse, detailing, and performance verification. The draft of the standard has been subjected to a series of committee ballots, and presently is being formatted for Public Ballot. Therefore, it still is a draft that could undergo revisions. This paper describes the history of the standard and summarizes its contents as they stand as of this writing.
