Abstract:Based on the theoretical basis of construction simulation analysis of a tension structure, the steps of cable system tension for the spoke tension structure in Changchun Olympic Park Stadium were introduced. The finite element software ANSYS was used to simulate the three stages in the construction process including the back cable installation, synchronous lifting of ring cable and valley cable tension. During the tension process, the cable force was stable and no jump occurred. The configuration of the structure finally reached the forming target state, and the von Mises stress of the steel structure was small.
Keywords:Changchun Olympic Park Stadium; spoke tension structure; construction simulation; finite element analysis
