摘要
采用有限元方法对全加劲两侧开缝钢板剪力墙在面内水平荷载作用下的弹性屈曲临界荷载、屈曲模态进行了研究。对影响其弹性屈曲性能的参数进行了分析,包括两侧和中部加劲肋与墙板的刚度比、两侧和中部加劲肋宽厚比以及墙板高厚比和边长比。给出了全加劲两侧开缝钢板剪力墙加劲肋的弹性屈曲设计参考公式,为开缝钢板剪力墙的应用提供依据。
Elastic buckling behavior of the stiffened steel plate shear wall slotted at two edges under in-plane lateral shear force is studied in this paper by employing numerical analysis method. Parameters affecting the elastic buckling behavior of the stiffened steel plate are investigated comprehensively. These parameters include stiffness ratios of both edge and inter-mediate stiffeners to infill steel plate, slenderness ratio of infill steel plate, and aspect ratio of infill steel plate. Based on the numerical studies, elastic buckling coefficients of stiffened steel plate shear walls slotted at two edges are pro-posed
and some helpful conclusions are drawn for the desig of this type of stiffened steel
shear wall system.
