RC框架中柱失效下的抗连续倒塌研究进展

Research progress of progressive collapse on reinforced concrete frame structures under a middle column removal scenario

钢筋混凝土 （RC）框架结构作为一种常见的结构形式,其连续倒塌事件的发生给人民生命财产造成了巨大 的损失.近几十年来针对RC框架的抗连续倒塌问题,国内外学者进行了诸多方面的研究.文章从RC框架抗连续倒 塌的理论研究和试验研究现状两个方面进行了归纳和总结,尤其是近10年的研究进展,得出了一些结论并对未来 所需解决问题做了展望.

As one of most common structures, progressive collapse of reinforced concrete structures causes serious biotic and economic losses. A lot of researches about collapse of reinforced concrete frame structures have been done by domestic and foreign scholars for several decades. Progressive of progressive collapse theory and tests on reinforced concrete frame structures, especially achievements in recent 10 years have been summarized in this paper. Finally, the important research problems are prospected.
