摘要
结构倒塌分析主要涉及三个难点,即不连续位移场的描述、接触碰撞分析以及结构倒塌过程中大位移、大转动的描述。本文就国内外研究现状针对结构倒塌的评定标准以及上述三个难点做出评述,同时介绍了作者近期工作,并对今后研究工作做了展望,以供参考。
There are three major difficulties in structural collapse analysis, namely the description of discontinuous displacements, contact-collision analysis and description of large displacement and large rotation arisen in collapse process. It is provided in this paper the comments on the current research focusing on the aforementioned points plus the collapse criteria. At the same time, the work done by the authors is also presented in brief. And so are the prospects of the future research in collapse analysis, as for reference.
