摘要
蚌埠龙湖体育馆为平板网架结构,正交预应力空间桁架为屋顶主要受力构件。介绍了双向体外预应力钢结构及其节点设计和施工技术。采用有限元计算软件MIDAS/gen对钢结构应力和变形进行仿真计算,并对相应应力和变形进行现场监测。结合施工仿真计算结果和现场监测结果,提出了此类结构的预应力及钢结构施工方案。
Plane grid structure was used in Bengbu Longhu Gymnasium, and orthogonal spatial prestressed truss was adopted as main roof bearing components. Design and construction technology of bidirectional external prestressed steel structure and corresponding joints were introduced in this paper. Steel stress and deformation were simulated by MIDAS/gen software, and they were also monitored on-site. Based on the calculated and monitored data, construction scheme for prestressed steel structure is proposed.
