Mechanics Simulation and Analysis of the Main Palaestra of the World University Games during the Unloading Process

Abstract:

The steel roof of main palaestra of the World University Games is a long span space structure of single-layer fold face reticulated shells. The space positioning installation of members of this structure is very difficult, and the control accuracy is very high. In order to improving the installation accuracy of this space structure during the construction, a method named bulk-way assembly technology at high altitude with multi-points supporting had been adopted. After the closure of the steel roof structure the temporary supporting jigs began to be uploaded. During this process the supporting jigs quit work gradually and the main structure began to carry the load. Different uploading way will make different influence for the main structure and supporting jigs during the uploading process. These have to be considered in the structural design and construction stage. This article adopts construction mechanics and FEA method to analyze the uploading procedures according to the real construction process in order to finding the actual internal force and deformation and ensuring the security of the structure and supporting jigs. Lots of results have been obtained as guidelines in theory for the design and construction.
