[摘要] 介紹了美國國防部在2009年出版的用于結(jié)構(gòu)抗連續(xù)倒塌的設(shè)計(jì)準(zhǔn)則UFC 2009。與以前的版本(UFC2005)相比，UFC 2009作了較大的修訂，主要體現(xiàn)在以下幾個(gè)方面：判定結(jié)構(gòu)抗連續(xù)倒塌要求的方法、拉結(jié)力法、備用荷載路徑法、改進(jìn)的局部抗力法，分析方法。本文有助于理解UFC 2009設(shè)計(jì)準(zhǔn)則，并期望為相關(guān)的科研選題提供參考。

Abstract: The code for the progressive collapse design, UFC 2009, was introduced. Compared with UFC 2005, UFC 2009 was revised greatly in the following ways: the method to define the buildings' progressive collapse requirements, tying force approach, altemate path method and enhanced local resistance. The provisions in UFC 2009 were introduced to understand UFC 2009 and provide reference for the related research.
Keywords: progressive collapse; tying force approach; altemate path method
