| 摘 要： | 采用MIDAS／Gen对两个五层1：3缩尺模型进行了静力弹塑性分析（pushover分析），得到了改进型交错桁架（与一般形式的交错桁架相比）结构体系的极限承载力较大，结构体系的薄弱层由底层向第二层转移，结构的整体刚度分布趋于合理，为交错桁架的研究提供了参考。

| Abstract: | Two One-third scale specimens of five story composite staggered truss structures were designed by in this paper,and then pushover analysis was proceeded by finite element program MIDAS/Gen,the beating capacity of the reformed composite staggered trusses system is large;the weakness storey was transferred to second floor,the distribution of stiffness became rational,the above-mentioned conclusions can lay a good foundation and provide basis for further research. |
