Abstract
In order to work out the problem of insufficient bearing capacity for large span space structure, the structural model optimization design and fabrication process were researched by using Structure Analysis Program 2000(SAP2000) and Finite Element Analysis Software (ANSYS). The model strength, rigidity deformation and stability analysis were calculated respectively according to the software. A series of innovative work during the design and manufacture process of the entire model were carried out, finally by designing and making large-span spatial structure model and loading test, the loading characteristics of large-span spatial structure were gotten, and some design advice were put forward.
