The Application And Research Of Long Span Structure In Hangzhou Grang Theatre

In this thesis, combining with the Hangzhou Grand Theatre, some kinds of long span structure were analyzed. Because of the especial requirement and architectural function, the long span structures were widely applied in the Hangzhou Grand Theatre. For example, the back roof of hyperboloid ellipsoid was built with the steel spatial reticulated shell, and the glass curtain wall of the front roof of conical shell was constructed with the spatial steel truss, as well as, the pre-stressed concrete structures were applied in the stage and the auditorium.Firstly, the static behaviour of the complex reticulated shell structure which was composed of hyperboloid shell and inverted conical shell has been studied. The complex reticulated shell structure was novel and beautiful in architectural form, However, its local conformation and fixing types were complicated. a comprehensive analysis was finished to this structure, and the structure style, FEA model, load cases and its combination were introduced. For various kinds of loading case, the static analysis were conducted with the finite element commercial software ANSYS. Secondly, the glass curtain wall of the front roof of conical shell was studied. Based on three structure schemes, their strength and deformation were calculated and evaluated. A special joint form between the steel truss and the roof steel truss was presented. Thirdly, the optimization design of the pre-stressed concrete structure of the auditorium and stage were performed. Considering construction process, the multi-layer pre-stressed concrete frame of the main stage was analyzed. The result of onsite test ofthe pre-stressed concrete structure was discussed.Finally, some conclusions were summarized and the problems that should be studied further were put forward in the end of the article.
