摘要
上海科技大学体育馆采用预应力张弦梁结构形式的屋盖,投影长90.8m,横向跨度51.2m,由10榀张弦梁、2榀托桁架、2榀钢箱梁、主桁架及边桁架形成整体框架,交叉次梁进行连接。结构复杂,施工难度大。介绍了上海科技大学体育馆张弦梁施工过程中的吊装、临时支撑、数值模拟及张拉等技术措施。
Shanghai Technical University Gymnasium uses beam string roof with 90. 8m length and 51. 2m span,which composite of ten string beams,two support trusses,two steel box beams,main truss and side truss and these components are connected by cross secondary beam. The structure is complex and the construction is difficult. This paper mainly introduces some technical measures of hoisting,temporary supports,simulation and tensioning during construction of beam string roof in Shanghai Technical University Gymnasium.
