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(pusbover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.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 bearing 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.

关 键 词：钢结构交错桁架 刚度 PUSHOVER分析
