| 摘 要： | 介绍自由侧边时带缝钢板剪力墙初始抗侧刚度的推导过程和理论根据,提出了缝宽剪切刚度减小系数,并对墙板进入塑性后的刚度退化进行理论探讨;对带缝钢板剪力墙平面外失稳和抗剪极限承载力这两种极限状态进行分析;通过有限元分析,指出竖向荷载、开缝参数等对四边固定带缝钢板剪力墙弹性屈曲临界力的影响,提出提高带缝钢板剪力墙实际工作效率的设想。

| Abstract: | Based on the theoretical analysis of the distortion characteristic of steel shear wall with slits,the formula of initial lateral stiffness and how to get the formula is described.By the theoretical analyses,a coefficient reflecting the influence of the slit width is gained.In addition,the reducing of lateral stiffness to steel shear wall with slits after some of the wall plate entering plastic is discussed.Through the finite element analysis to wall plate with four side fixed,this article had pointed out the influence of the vertical load,the slit parameter and so on,to the elastic buckling strength of the steel shear wall with slit,and proposed the tentative plan that enhances the work efficiency of the steel shear wall with slit. |
