摘要

本文首先验证了ADINA有限元软件进行带缝钢板剪力墙数值模拟的可行性,然后将普通开缝钢板剪力墙与无缝钢板剪力墙进行对比,分析了两者在受力性能上的优缺点。建立了3种不同开缝形式的钢板剪力墙,对其施加水平往复荷载,对比分析它们的初始抗侧刚度、屈服荷载、延性系数、极限承载力等,提取了往复荷载作用下的滞回曲线和骨架曲线,分析了各开缝形式的应力、应变云图,研究了不同开缝形式对其受力性能的影响,从而找出了较佳的开缝方式。
First,the feasibility of numerical simulation on steel plate shear wall with slits using ADINA finite element software is verified in this article,then steel plate shear wall with slits and steel plate shear wall are compared,the advantages and disadvantages on performance of them are analyzed. Three different forms of steel plate shear wall with slits are established,horizontal reciprocating load is applied on them. Initial lateral stiffness,yield load,ductility coefficient,ultimate bearing capacity,etc are compared and analyzed. The hysteretic curve and skeleton curve under reciprocating load are extracted,and the stress nephogram and strain nephogram of models are analyzed. The effect of different forms of slits on the properties of the steel plate shear wall is studied,the better slits mode is found at last.
