Abstract:
According to the steel tonnage of National Stadium large-span roof steel structure being relatively large in the original preliminary design, the load bearing capacity and connection characteristics of the structure were improved greatly by means of re-adjustment of the primary structure and secondary structure. The suitable design method for thin-wall weld box section was presented based on the stress analysis of the panels of box sections. According to the structural characteristics of the main truss structure and the secondary structure, the calculation length factors of the compressed members were defined reasonably. Panel by panel erection scheme for the roof structure was presented and the locations of temporary supporting towers were arranged reasonably, the effect of construction procedure on the seismic resisting capacity of the structure was also included in the soon. The proper choice of the domestic high-strength steel reduced the total weight of the structure effectively. In order to satisfy the requirements of the complicated large-span steel structure design of National Stadium, the design and optimization functions were developed based on ANSYS software platform. Feasibility of the prestressed techniques was studied through the comprehensive comparison between several cable arranging schemes. All those effective optimization measures reduced the steel tonnage of National Stadium large-span steel structure and the significant technology; social economic benefits were achieved.
