结构工程抗倒塌设计研究综述

Overview of Research on Collapse-resistant Design in Structure Engineering

分析了地震、爆炸、冲击等造成结构倒塌的原因,指出了倒塌结构在设计、施工等方面存在的问题;归纳了现行规范在抗倒塌设计方面的相关内容,特别指出了中国规范在这方面的不足;总结了现有的破坏准则和抗倒塌设计方法,指出了其中的不足;最后从破坏准则、设计方法、规范修订等多个方面对今后的研究工作做了展望。

The reasons of collapse of structure under the special loads were analyzed,such as earthquake,blast,impact,and so on.The existing problems in design and construction of the collapsed structures were pointed out.The related contents about the collapse-resistant design of the existing codes were summarized,and the deficiencies of Chinese codes were pointed out in this regard.The existing failure criteria and collapse-resistant design methods were summed up,and their deficiencies were proposed.Finally,the prospects of the future research in collapse analysis were presented from failure criteria,design method and code amendment.
