摘要
洛阳新区体育中心体育场钢结构屋面罩棚工程采用桅杆支撑的预应力斜拉索桁架结构体系。通过采用ANSYS有限元分析软件进行全施工过程模拟计算分析,准确获得了洛阳体育场拉索索长、各施工阶段拉索索力及变形等施工参数,并据此制定了切实可行的施工方案。施工过程中采用分级张拉并进行施工监控,确保工程施工质量满足设计及有关施工规范要求。实践证明,对于索结构等非线性强的结构施工,必须对施工过程的结构和构件变形进行全过程测量和监控。
Prestressed stayed cable truss system supported by mast was adopted in steel awning engineering of Sports Center Stadium of Luoyang new district. Based on whole construction process simulation analysis by ANSYS software, construction parameters including cable length, cable force and structural displacement and so on were got. Multi-degree tension and construction monitoring scheme was made to ensure construction quality. Practice shows that whole process measuring and monitoring of structure displacement should be done, especially for cable structure and intensive nonlinear structure.
