恐怖爆炸下建筑物连续性倒塌研究进展
|
摘要
爆炸袭击是当前恐怖活动中最经常也是危害最大的一种方式,是造成建筑物连续性倒塌的最主要原因。近年来,随着恐怖活动的日益猖獗,建筑物连续性倒塌越来越受到工程界的关注,并已成为一个研究热点。回顾了建筑物连续性倒塌研究的历史,明确了建筑物连续性倒塌的定义、原因及其分析目的与流程。归纳分析了目前连续倒塌分析的几种方法:备用荷载路径法、局部抵抗特殊荷载法、构造设计法以及连续性倒塌仿真,详细阐述了备用荷载路径法。提出了对今后研究方向和难点的思考。
Terrible explosion is the most frequent and destroyable approach in terrible activities nowadays,which is the main reason to structure progressive collapse.At present,as the terrible activities is of high frequency,the progressive collapse of structures attracts more and more attention in engineering field and becomes a hotspot for study.The history of the structure progressive collapse is reviewed,and the definition as well as the reason,the analysis intention and analysis process are nailed down.The methods of progressive alternate load path,local resistance,concept design and simulation are summarized and analyzed,the alternate load path is emphasized.At last,the direction and difficulty of progressive collapse are put forward.
