大跨度玻璃幕墙不同支撑条件下立柱抗风压性能研究

Research on wind pressure resistance of columns under different support conditions of large-span glass curtain wall

大跨度玻璃幕墙由于其跨距大,在承受风载荷作用下,支撑体系如立柱会发生较大的挠度变形,产生较大的安全风险。本文通过对大跨度玻璃幕墙工程进行实例分析,对采用单跨和双跨形式的抗风压性能进行分析研究,从而对大跨度玻璃幕墙的型材选用及结构形式选择提供参考。

Due to large span of large span glass curtain wall,the supporting system such as column will have large deflection and deformation under the action of wind load,resulting in large safety risk. Through the case analysis of large span glass curtain wall project,this paper has analyzed and studied the wind pressure resistance of single span and double span,so as to provide reference for the selection of profile and structural form of large span glass curtain wall.
