单跨混凝土框架倒塌机理分析

摘要

Taking a single-span concrete frame for example,the collapse mechanism of this structure is studied by the means of Pushover.Based on the damage characteristics of single-span concrete frames in earthquake,the influence of cast-in-suit slab and ground are%以一单跨混凝土框架为例,采用Pushover方法分析了其倒塌机理,结合已往地震中该类建筑的破坏特征,研究了现浇板及结构地坪的影响,并简单介绍了目前针对该类建筑的几种常用加固方法,以指导工程实践。
