Abstract:The lower part of the gymnasium of Jinqiang International Sports Center is reinforced concrete frame-shear wall structure, and the upper part is  elliptical double-slope steel roof which adopts square space grids composed of two-way orthogonal plane trusses, with a maximum span of 109.700m. The detailed comparison was conducted of the schemes of the main structure, the large-span roof steel structure and bearings. The key issues involved in the analysis and design were introduced emphacically. A variety of finite element programs were used to conduct the overall mechanical analysis of the structure under various loading working conditions and the key nodes of the structure were also analyzed. The analysis results show that the structure can meet the preset performance goals, and the stress ratio, deformation and overall stability of the roof components can meet the design requirements.
