摘要
本文基于某活动中心网架结构维修改造可行性为目的,采用有限元分析软件M idas建立该网架的空间有限元模型,考虑橡胶支座刚度和维修改造产生的荷载变化,对网架结构的承载能力进行验算,从而确定改造的可行性。
In this paper, the three- dimensional finite element mode （FEM） of a large- span grid structure was established by using the finite element program Midas, and the bearing capacity analysis for reconstruction feasibility of this structure in the FEM with consideration of the horizontal stiffness of rubber bearing and the load - change after reconstruction was performed.
