摘  要: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 behavior of diagonally stiffened steel plate shear wall with connections was studied by employing finite element analysis software ANSYS. Special attention on the influence of the parameters on the buckling coefficient of the panel. These parameters two-side was paid included stiffness ratio of stiffener to panel, to thickness ratio of stiffener. The depth-thickness ratio of the panel, aspect ratio of the panel, and width results show that the diagonal stiffener can significantly increase the elastic buckling load of the steel plate shear wall, and its influence is greater than that of the cross stiffener. With the increasing of aspect ratio and depth-thickness ratio of the panel, the b is decreasing gradually. The smaller width to thickness ratio of stiffener can obtain buckling coefficient. Finally, the formulas were given to predict the buckling coefficient stiffened steel plate shear wall with two-side connections. uckling coefficient the larger elastic of the diagonally
