| 摘 要： | 本文对4种钢框架、6种带缝(两排)钢板剪力墙片(四周与构件无连接)和6种固接的钢框架-带缝钢板剪力墙结构在3种不同竖向荷载作用下的抗侧能力和往复荷载下的滞回性能进行了研究,并对比分析。结果表明:前两种结构的侧移刚度、抗侧能力相对较低,屈曲后刚度退化快;钢框架-带缝钢板剪力墙结构的侧移刚度、抗侧能力和耗能能力比前两种结构有明显的提高,说明钢框架与带缝钢板剪力墙片固接后工作协调性能良好。带缝钢板剪力墙片与钢框架-带缝钢板剪力墙结构的整体设计参数宽高比W/H,开缝设计参数开缝墙肢的高宽比h/b、宽厚比b/t、开缝墙肢与剪力墙的高宽比h/H对结构的抗侧能力和滞回性能有很大影响。W/H增大,结构的抗侧能力增强,滞回性能降低;h/b、b/t、h/H增大,结构的抗侧能力降低,滞回性能提高。

| Abstract: | The lateral resistant ability under three kinds of vertical loads and the hysteretic performance under cyclic loading are analyzed and contrasted for four steel frames,six steel plates shear wall piece with slits(two rows) and six steel frames-steel plate shear wall with slits.The results show that the lateral stiffness and lateral resistant ability of the first two kinds of structures are lower than steel frames-steel plate shear wall with slits.The stiffness is also degenerated quickly after buckling;the lateral stiffness,lateral resistant ability and energy dissipating ability of the steel frame-steel plate shear wall with slits have distinct enhancement as compared to the first two kind of structures.The coordinating performance of four-side fixed steel frame and steel plate shear wall piece with slits are excellent.The design parameters of the steel plate shear wall piece with slits and the steel frame-steel plate shear wall with slits have significant influence on the lateral resistant ability and hysteretic performance of the structure,such as the width/height ratio of the shear wall W/H,the height/width ratio of wall limb with slits h/b,the width/thick ratio of wall limb with slits h/t,the ratio of the height of wall limb with slits to the height of shear wall h/H.When W/H increases,the structure's lateral resistant ability developed,hysteretic performance is lowered.When h/b,b/t,h/H increase,the structure's lateral resistant ability loses,and the hysteretic performance is improved. |
