摘要
本文介绍了近年来框架和冷弯型钢构件稳定承载力计算的新问题和新方法,包括框架先进分析法的实用化,当前广泛应用的计算长度法的改进,弱支撑框架和半刚性连接框架的稳定,大跨度框架无侧移失稳的可能性和计算方法,陡坡山形门式刚架的稳定,冷弯薄壁型钢板件局部相关屈曲,开口截面的畸变屈曲,以及局部和整体的相关屈曲。
Recent issues and new approaches relevant to the calculation of stability capacity of frames and cold--formed thin--walled mem-
bers are introduced in this article, such as practical advanced analysis for frame design, improvement of the effective length ap-
proach widely in use at the present time, stability of the frames supported with weak bracing system and those with semi--rigid
connections,possibility of large-span frames to buckle without lateral sway and the relevant calculation method, buckling of
steeply pitched portal frames, interactive buckling of plate elements in cold--formed thin--walled members,distortional buckling
of thin--walled open sections and interaction of local and global buckling.
