Abstract:
The beam membrane structure of the single-layer spherical reticulated shell is analysed,and thestrength and local stability of reticulated shell structure design criterion are determined according to the failureforms of shell. The fluid solid coupling analysis of wind field and structure field is used through the finite ele-ment analysis software,and the section size optimization of the member is got by optimizing design.Through themulti point load test of the prototype of reticulated shell structure，the maximum displacement curve changeswith 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 thesame type of single-layer spherical reticulated shell.
