摘要
当前,多起桥梁结构的倒塌事故造成严重的生命财产损失,严重危害公共交通安全.因此,极端作用下的桥梁结构连续倒塌研究迫在眉睫.根据极端作用的概念定义,简要分析了极端作用下的国内、外的多起桥梁连续倒塌事故的原因,针对桥梁结构抗连续倒塌的研究现状进行综述.根据相关研究发现,桥梁结构的抗连续倒塌研究不同于建筑结构,有其自身的特点,因此,应建立自己的研究体系并制定相关规程等.
At present, bridge structural accidents cause serious loss of life and property and serious damage to public traffic safety. Therefore, it is imminent to research on progressive collapse for bridge structure under extreme load. From the concept of extreme load, probable causes of progressive collapsed case for bridges both here and abroad are analyzed briefly, the research status of anti-progressive collapse analysis for bridge structures is summarized. According to relevant researches, it shows that the study of progressive collapse for bridge structures can not be exactly equal to that of the building structure. So the research system for bridge structural progressive collapse should be built up, corresponding specifications is also needed to develop, etc.
