| 摘 要： | 钢 混凝土组合深梁填充钢框架是一种新型抗侧力结构体系。用有限元分析软件SAP2000对6层钢框架和6层钢框架填充组合深梁进行了动力非线性时程分析，得到结构的顶点位移、基底剪力、层间位移角、楼层位移及塑性铰发展情况。通过对比分析发现，钢框架内填深梁以后，结构刚度和承载能力增强，且深梁首先破坏，保证钢框架安全，充分起到了抗震第一道防线的作用。

| Abstract: | Steel concrete composite deep beam infilled steel frame is a new kind of structure. SAP2000 is used for nonlinear time history analysis of six story steel frame and six story steel frame infilled with composite deep beam. The displacement of the top point, the shear of base,the inter storey displacement angle,the displacement of the story and the development of the plastic hinge are obtained. After infill of deep beams, it is found that structure stiffness and carrying capacity become stronger, and deep beam destroys first, keeping the frame safe and playing a role of first resistance against earthquake. |
