加劲钢板剪力墙抗剪性能分析

利用ANSYS有限元软件对交叉加劲钢板剪力墙的抗剪性能进行了研究,重点分析了肋板刚度比和加劲肋宽厚比对剪力墙荷载—位移曲线的影响。研究表明,设置交叉加劲肋能够显著提高钢板剪力墙的承载能力;肋板刚度比对于厚板和薄板抗剪性能的影响不同,对薄板的影响大于厚板;然而无论是厚板还是薄板,加劲肋宽厚比对于墙板荷载—位移曲线的影响都很小。

SHEAR RESISTANCE BEHAVIOR OF STIFFENED STEEL PLATE SHEAR WALL

The shear resistance behavior of diagonally stiffened steel plate shear wall was studied by employing finite element analysis software ANSYS.Special attention was paid on the influence of the parameters on the load-displacement curve of the panel.These parameters included stiffness ratio of stiffener to panel,depth-thickness ratio of the panel,and width to thickness ratio of stiffener.The results show that the diagonal stiffener can significantly increase the bearing capacity of the steel plate shear wall.The stiffness ratio of stiffener to panel produces different effects on shear resistance behavior between the thick panel and thin panel.However,no matter thick panel or thin panel,width to thickness ratio of stiffener has slight effects on load-displacement curve of them.
