预应力钢管桁架在北京外国语大学体育馆工程中的应用

APPLICATION OF PRESTRESSED STEEL TUBE TRUSS IN BEIJING FOREIGN STUDIES UNIVERSITY GYMNASIUM ENGINEERING

在很多大跨度、大面积楼层结构设计的方案中,如单纯使用钢筋混凝土结构,会存在结构截面尺寸大,占有空间多、自重大,满足不了建筑物的功能需要等问题,采用预应力钢管桁架来拾遗补缺,能有效解决结构大跨度、高承载力、大自重、大截面尺寸、杆件挠度和占用空间多的矛盾。通过北京外国语大学大学生体育馆工程,详细介绍预应力钢管桁架在大跨度建筑工程中的施工工艺。

In many structure design solutions of large-span and large-area floor, such as pure application of reinforced concrete structure, there may be such problems as large structural cross section, huge space occupation, heavy self weight and dissatisfaction of building function, etc. These problems can be overcome by adopting prestressed steel tube truss. Taking Beijing Foreign Studies University student＇s gymnasium engineering as an example, construction technology of prestressed steel tube truss in large-span architectural engineering is introduced in details.
