摘要
采用有限元软件MIDAS/GEN,对某单层网壳结构进行了各荷载工况组合下的计算分析,得到了结构受力、变形和稳定性能,并基于多尺度分析方法,将节点细部模型与结构整体宏观模型连接,在整体模型中对结构复杂节点进行了计算分析,有效提高了计算精度。
The paper adopts the finite element software MIDAS / GEN to have the calculation analysis of the single-layer latticed structure under combination with various loadings,concludes the structural stress,deformation,and stability performance,integrates the joint detail model and structural macromodel based on the multiscale analysis,and undertakes the calculation and analysis of the structural complicated joints in the integrated model,so as to improve the calculation accuracy.
