该文进行了5个开缝钢板剪力墙在滞回荷载作用下的试验研究,着重研究了钢板剪力墙开缝排数对其力学性能的影响,同时考虑了钢板跨高比和钢板与框架梁连接方式的影响。试验结果表明:两边连接开缝钢板剪力墙具有良好的滞回性能;在弹性阶段,钢板以整体变形为主;进入弹塑性阶段,钢板由整体屈曲变形逐步过渡到以小柱弯扭屈曲为主的变形。构件的最终破坏模式表现为小柱端部撕裂或墙板端部撕裂。钢板开缝排数对剪力墙力学性能的影响较小。已有的研究结果表明:剪力墙的力学性能主要和缝间小柱的宽厚比和高宽比有关,当宽厚比小于15且高宽比大于3时,开缝钢板剪力墙具有良好的滞回性能,缝间小柱端部形成塑性铰耗能,基本能达到理想的平面内工作状态。
In this paper, the experimental study of five open shear walls under the effect of hysteretic load is carried out. The influence of the number of rows and columns on the mechanical properties of the shear wall is emphatically studied. Effect of Frame Beam Connection Method. The experimental results show that the shear walls connected with slitted steel plates on both sides have good hysteretic behavior. During the elastic phase, the steel plate is mainly deformed as a whole. When the plate enters the elasto-plastic stage, the plate undergoes a gradual transition from overall buckling to buckling The deformation of the Lord. The ultimate failure mode of the component is the tearing of the post end or the tearing of the end of the wallboard. The number of steel plate slits has little effect on the mechanical properties of the shear wall. The existing research results show that the mechanical properties of the shear wall are mainly related to the aspect ratio and the aspect ratio of the slit between the joints. When the aspect ratio is less than 15 and the aspect ratio is more than 3, the slitted steel plate shear wall has good Hysteresis performance, the end of the slot between the plastic hinge hinge to form energy consumption, the basic can achieve the ideal state of work plane.
