摘要
滨江高级中学体育运动中心是综合性的体育馆。根据建筑的平面跨度及方案要求,在比较了空间立体桁架、张弦梁结构、空间网架结构的基础上,屋面最终选择了简洁美观、方便施工的正放四角锥网架结构。为减小跨中挠度,结合屋面建筑造型特点,屋面一端采用大悬挑网架并与主屋盖连为整体,该结构形式完全能符合受力性能要求。体育运动中心下部采用钢筋混凝土框架结构。文章介绍了该工程的结构体系的确定,根据设计难点及超限情况,采取相应的结构措施。详细介绍了结构抗震性能化设计过程,以及大跨度钢屋盖与主体结构的设计。采取有效措施,解决了结构超长、温度应力等问题。结果表明,该结构计算结果均能满足规范要求。
Binjiang senior high school Sport Center is a comprehensive gymnasium.According to the plan span and scheme requirements of the building,based on the comparison of space truss,beam string structure and space grid structure,the square pyramid grid structure,which is simple,beautiful and convenient for construction,is finally selected for the roof.To reduce mid span deflection,combined with the characteristics of roof building modeling,one end of the roof adopts large cantilever grid and is connected with the main roof as a whole,this structural form can fully meet the requirements of mechanical performance.Concrete frame structure is adopted for the lower part of the Sports Center.The determination of the structural system were introduced.According to design difficulties and transfinite category,corresponding structural measures were adopted.The seismic performance-based design process of the structure is introduced in detail,and the design of large-span steel roof and main structure.Effective measures were taken to solve the problems of super-long structure and temperature stress.The results show that,the calculation results of the structure can meet the requirements of the specifications.
