钢框架结构吊柱逆做和顺做施工方案

Construction schemes of hanging columns by top-down and bottom-up method in steel frame structure

对钢框架结构屋顶桁架下挂吊柱的逆做法和顺做法两种施工方案进行了论述,阐明钢框架、屋顶钢桁架、吊柱构件的施工流程,分析两种方案的工期和对结构受力变形的影响,进行方案的选择。

In this paper,two construction schemes of hanging column under steel frame roof truss are discussed.The construction flow of steel frame,roof steel truss and hanging column member is expounded.The construction period of the two schemes and the influence on the stress deformation of the structure are analyzed.And the scheme is selected.
