摘要

摘要: 从保证柱列纵向稳定性的角度，对竖向荷载作用下交叉支撑的刚度要求进行研究。介绍无初始几何缺陷的单、双层纵向柱列支撑体系的抗侧刚度要求；根据实际框架中的各种初始几何缺陷，考虑竖向荷载的P-与P-二阶效应，利用有限元程序ANSYS对承受竖向荷载作用的单、双层纵向柱列支撑体系进行受力分析，据此确定用于设计的竖向荷载作用下单、双层纵向柱列支撑体系的交叉支撑刚度要求的计算公式，为传统的交叉支撑由纵向水平受力决定的设计方法补充竖向受力分析的验算方法。

Abstract: The stiffness requirements of the diagonal bracings in order to maintain the stability of longitudinal columns under the only vertical loads have been investigated in this paper.The lateral stiffness requirements of one-story and two-story longitudinal column-bracing systems without the initial imperfections were introduced.One-story and two-story longitudinal column-bracing systems under the only vertical loads were analyzed using the ANSYS program,in which two order effects on P- and P- were well considered according to the initial imperfections of the actual frames.According to the analysis results,the design formulas of stiffness requirements of the diagonal bracings for one-story and two-story longitudinal column-bracing systems were obtained,and a check method based on the vertical loading analysis was supplied for the diagonal bracings,which is usually designed by the longitudinal horizontal loads.
