地震作用下结构连续性倒塌研究进展与展望

Research progress and prospect of progressive collapse of structure under earthquake action

近年来,地震灾害频发,导致结构倒塌事故时有发生,造成重大的人员伤亡和经济损失。针对地震作用下结构倒塌破坏,国内外学者进行了诸多的研究工作。从倒塌破坏准则、结构倒塌与抗倒塌试验、结构倒塌数值模拟和结构抗倒塌措施四个方面,对结构连续性倒塌的研究现状进行了归纳和总结,并对未来的研究热点进行了展望。

Owing to accidental disaster of earthquake, the collapse events of structures have often happened in re- cent years, which led to heavy casualties and serious economic losses. A lot of researches about collapse of struc- ture under earthquake action have been done by domestic and foreign scholars. The present research conditions of collapse of structure are introduced and summarized collapse damage criteria, collapse and collapse resistance ex- periment, collapse simulation and collapse resistance measures. Finally, the important research problems of col- lapse of structure are prospected.
