摘要
在竖向荷载作用下 ,山形门式单层多跨刚架平面内可能产生两种整体分岔屈曲模式 ,一种是侧移屈曲 ,另一种是跃越屈曲。介绍了影响刚架屈曲的拱效应和为避免发生整体屈曲的准则。
Under transverse load,two overall in plane buckling modes may be occurred,one is sway buckling and the other is snapthrough buckling This paper illustrates the arching effect influencing the frame and the criteria for avoiding the overall buckling of single storey pitched roof frames
