Structure design this paper to aluminum ore yard proof shelter as the background, the load-bearing structure with steel pipe frame, frame beams and columns are used spatial truss form triangular cross section. Using the software PKPM and large-scale general finite element analysis software ANSYS respectively the internal force analysis and the cast steel node analysis of bearing capacity of structure analysis, specific as follows: Put forward the design principle and the theoretical basis of pipe truss structure. By using PKPM software, established the 3D model of steel frame structure, and has carried on the detailed analysis of internal force. Using finite element analysis software ANSYS, established the frame beam, column steel pipe truss pieces connected node model
