摘要
目前《门式刚架轻型房屋钢结构技术规程》将门式刚架空间结构体系简化为平面结构体系进行计算,没有考虑横向水平支撑和纵向柱间支撑的整体作用。采用通用有限元软件 SAP2000,对局部双层四跨门式刚架厂房进行空间和平面非线性静力和施工过程分析,并进行比较,发现某些情况下必须采用空间计算,否则会造成较大误差,且偏于不安全。
The specification CECS 102:2002 which do not consider horizontal bracing and column bracing predigest light- weight buildings to plane frame. SAP2000 is used to do finite element analysis of nonlinear static and construction process in this paper. The comparative analysis is made between space model and plane model. If the special calculation could not be done, the results may be insecure.
