| 摘 要： | 为了研究钢框架连续倒塌动力效应,采用瞬时加载法对平面和空间钢框架柱失效后动力效应进行了研究。采用基于等效塑性转角和等效竖向位移的荷载增大系数来衡量结构的动力效应,分析跨数、层数、高宽比、柱失效位置、节点转动刚度及空间作用等参数对结构动力效应的影响,研究成果可为抗连续倒塌设计提供参考。

| Abstract: | Study on dynamic effects following the column failure during progressive collapse,are carried out.The influences of the stories,spans,aspect ratio,column fuction loss position,joint rotational stiffness and space action on the dynamic effects are studied,which can be used as a basis for making a rational design code for structures during progressive collapse. |
