摘要
对单层球形网壳梁膜结构进行分析,根据网壳的失效形式确定网壳结构的强度和局部稳定性设计准则,利用有限元分析软件对风场和结构场流固耦合分析,并通过优化设计得到杆件最优截面尺寸.通过对原理样机网壳结构进行多点加载试验,得到最大位移点随载荷变化曲线,并把试验结果与仿真结果进行对比分析,对仿真计算模型进行验证,为同类型单层球形网壳的设计与分析提供理论基础.
The beam membrane structure of the single-layer spherical reticulated shell is analysed,and the strength and local stability of reticulated shell structure design criterion are determined according to the failure forms of shell. The fluid solid coupling analysis of wind field and structure field is used through the finite element analysis software,and the section size optimization of the member is got by optimizing design. Through the multi point load test of the prototype of reticulated shell structure,the maximum displacement curve changes with the load is obtained. Meanwhile,the test results and the simulation results are compared and analyzed,and the simulation calculation model is verified,providing theoretical basis for the design and analysis of the same type of single-layer spherical reticulated shell.
