MST was used to establish BIM model and checkthe coordinates of neighboring nodes.XSTEEL was used to model the node.ANSYS and SAP were used to conduct FEM analysisof nodes.MIDAS was calculate the deformation of the structure,especially the deflection of the roof, and thecoordinates of nodes were adjusted accordingly.3DMAX was used to simulate the construction process.
