Abstract：Tianshui City Exhibition Center structure belongs to the complicated high-rise building. Structure is reinforced concrete frame - shear wall, the reinforced concrete, reinforced concrete, steel and other structural form of com. In order to realize the architecture modeling and graphic function, the structure of different forms of. Analysis and design of seismic performance; design of large span steel structure, long cantilever structure design; force analysis and the design of super-long structure should be the floor temperature; reasonable construction measures is reasonable in structure design plays a key role.
