摘要
某幕墙支撑结构采用单层柱面网壳形式,结合建筑形态和结构性能确定了网格和构件截面形式,基于有限元软件SAP 2000和ANSYS,对网壳结构进行了特征值屈曲分析,得到了构件计算长度系数;同时进行了非线性全过程分析。结果表明,该网壳结构具有较好的整体稳定性。
Single-layer cylindrical latticed shell was adopted in a curtain wall support structure. Grid division and section furm were determined according to the architectural morphology and structure performance. Based on the finite element softwares SAP 2000 and ANSYS, the effective length factor of the slope column was obtained hv eigenvalne huekling analysis. Meanwhile, the nonlinear full-range analysis was conducted. The results indicated that the overall stahility of the structure could be assured.
