限制出平面屈曲开缝钢板剪力墙抗剪性能
|
摘要
为研究开缝对钢板剪力墙在横向力作用下的刚度、承载力、延性和滞回性能的影响,便于工程师在结构设计时对构件力学性能进行调整.采用ANSYS软件研究了在限制钢板出平面屈曲的情况下缝间小柱宽度b对开缝钢板剪力墙抗剪静力性能的影响,分析开缝钢板剪力墙的受力机理.研究结果表明:在限制钢板出平面屈曲的情况下,开缝钢板剪力墙各缝间小柱受力状态相近,且随其高宽比α变化有两种受力模式;开缝形式会影响开缝钢板剪力墙中框架对钢板的作用;改变开缝形式会影响钢板剪力墙的初始剪切刚度和承载力,但不能对二者进行分别调整.
To meet different structural demands,the static mechanical characteristics of the steel-plate shear wall with slits (SPSWS)with the limitation of out-of-plane buckling were analyzed using ANSYS. The influences of width b between each slit on the shear behaviour of SPSWS were investigated. It indicates that in the case of limiting the out-of-plane buckling,the stubs between slits behave similarly,and two mechanical modes exist with the variation of height-width ratio α of the stubs; slits arrangement influences the action situations of the adjacent frame to the steel componert in SPSWS; the initial shear stiffness and the load-bearing capacity of SPSWS can be changed simultaneously by adjusting the silts setting,however this effect is coupled and difficult to be separated.
