钢框架抗连续倒塌方法研究

Study on Anti-progressive Collapse Method of Steel Frame

近年来,建筑结构的抗连续倒塌正日益受到重视,所谓抗连续倒塌,即指结构遭遇意外事故(如冲击、爆炸、地震等情况)导致某根构件失效后结构能否继续使用而不发生大范围或者局部倒塌的能力,结构的抗连续倒塌已逐渐成为结构研究的热点。文章从钢框架结构抗连续倒塌这一角度出发,详细探讨如何提高钢框架抗连续倒塌能力,从而为结构设计做出一定的参考和借鉴意义。

In recent years, anti-progressive collapse of the building structure is attracting increasing attention,the so-called anti-progressive collapse is that the structure is subjected to accident（such as impact, explosion,earthquake, etc.） after a root cause failure of the structure member can continue to use without a wide range of ability or partial collapse occurred, anti-progressive collapse of the structure has become a hot research structure. From the steel frame structure progressive collapse that perspective, discussed in detail how to improve the steel frame progressive collapse, in order to make a reference for the structure design.
