Research On Structure Selection And Mechanical Property Of Jiaozhuo Taichi Gymnasium Roof

Since2008Beijing Olympic Games, our country sports enterprise vigorous development and the "sports population" vigorous growth has made our country sports venues of the construction is in a new gold stage. Comparing with the traditional structure, gymnasium structure have the characteristics of large-Span, the structure of complex and diverse. In addition, the structure design is difficult. And In some cases,it exists ultra-specification problems. Therefore, this article take Jiaozuo Taichi gymnasium roof for engineering background. and research on structure selection and mechanical property of the gymnasium roof.Specific content as follows:(1) According to the engineering construction scheme, in preliminary design scheme,use the two structural forms of space steel frames and space trusses. Through comparing the building function, force performance, economy and feasibility of construction confirming the final structure scheme.(2) For the selected structure, Using PMSAP and MIDAS/GEN software to structure analysis, comparing the main results of the analysis.,and verifying the structural modeling and analysis of the correctness of the process.(3) Egien buckling analysis and considering the initial defects of geometric nonlinear stability performance study to the structure.(4) Under the multi-earthquake, using the response spectrum and linear time history analysis of the structure, and compare the calculation results.(5) Under the rare earthquake, using the elastic-plastic time history analysis of the structure. through studying the plastic hinge development of structure, finding out the the weak positions the structure under strong earthquakes and evaluating the large-span roof structure seismic performance.
