采用ANSYS有限元软件对两边连接交叉加劲钢板剪力墙进行了弹性屈曲分析,重点研究了加劲肋与墙板的刚度比、墙板高厚比、边长比以及加劲肋宽厚比对弹性屈曲系数的影响,并将分析结果与十字加劲板进行了比较.研究表明,交叉加劲肋能够显著提高钢板剪力墙的弹性屈曲荷载,其远大于十字加劲肋;随着墙板边长比和高厚比的增大,屈曲系数趋于减小;而较小的加劲肋宽厚比能使墙板获得较大的屈曲系数;最后给出了两边连接交叉加劲板弹性屈曲系数的计算公式.
The elastic buckling analysis of the cross-stiffened shear wall connected with both sides was carried out by using ANSYS finite element software. The stiffness ratio of stiffener to wallboard, the ratio of wall thickness to thickness, ratio of edge length to stiffener, The results show that the cross stiffener can significantly increase the elastic buckling load of the steel plate shear wall, which is much larger than the cross stiffener. With the ratio of wall length to thickness and thickness The buckling coefficient tends to decrease, while the smaller stiffener aspect ratio can make the wallboard get larger buckling coefficient. Finally, the formula for calculating the elastic buckling coefficient of the cross stiffener attached to both sides is given.
