天津大学新校区综合体育馆结构设计

Structural design of Tianjin University gymnasium in the new campus

天津大学新校区综合体育馆结构高度为23.35m,采用了框架、框架-剪力墙结构体系,部分竖向构件采用锥筒柱,屋盖部分采用多种形式的混凝土拱壳。简要介绍了该工程的结构体系和弹性计算结果,对结构关键构件进行了补充分析,并通过特征值屈曲分析,阐述了构造措施对结构整体稳定和位移的影响,以及混凝土拱壳与竖向构件铰接连接、Y形转换框架柱、密梁空心楼板等关键技术的应用。

The structure height of Tianjin University gymnasium in the new campus is 23.35m. The frame structure and frame-shear wall strucuture are the based structure systems. The cone column is used for part of the vertical components. Various forms of the concrete shell was used for the roof. The structure system and the calculation results of elasticity of the project were introduced, key components of the structure were analyzed. Through the eigenvalue buckling analysis, the influence of structural measures on the whole strueture displacement and stability were discussed. The application of key technologies such as the concrete arch shell and the vertical member, the Y type conversion frame column and the hollow floor slab were discussed.
