摘要
以苏州中心8号和9号超高层建筑结构之间的大跨度钢桁架连廊为工程背景,对大跨度钢桁架结构受力性能进行分析.根据大跨度钢桁架连廊的工程特点,提出了大跨度钢桁架结构的计算模型,并采用SAP 2000有限元分析软件,对竖向荷载作用下各种类型钢桁架结构的内力进行了分析比较.此外分析了支座沉降作用下钢桁架结构的内力分布规律,得到了一些有益的结论,可为大跨度钢桁架安装施工监测提供技术依据.
The large span steel truss gallery between 8and 9super-tall building of Suzhou Center is taken as engineering background,the mechanical behavior of large span steel truss structure is analyzed.According to the engineering characteristics of large span steel truss gallery,the calculation model of large span steel truss structure is put forward.The internal forces of various types steel truss structure are analyzed by using the finite element analysis software SAP 2000.At the same time,the internal force distribution law of the steel truss structure is analyzed under the support settlement action.Some useful conclusions were obtained,which can provide technical basis for the construction monitoring of large span steel truss.
