中文摘要 | 防屈曲钢板剪力墙是一种新型的高层建筑钢结构抗侧力构件。采用数值方法对防屈曲钢板剪力墙在水平荷载作用下的弹性侧移刚度、抗剪极限承载力以及在低周往复荷载下的滞回性能进行了研究,提出了防屈曲钢板墙抗剪极限承载力以及弹性抗侧刚度的计算公式,供设计参考。对防屈曲钢板墙与普通钢板墙的滞回性能分析表明,防屈曲钢板墙可以显著改善普通钢板墙滞回曲线的捏拢现象,表现出更强的延性和稳定的耗能能力,是一种非常适合于高烈度抗震设防区的抗侧力体系。; Steel Plate Shear Wall (SPSW) has been used increasingly in Asia and North America as part of the lateral force resisting system over the last three decades. The main disadvantage of SPSW relates to service problems such as buckling sounds and out-of-plane displacement. The pinching shape in hysteretic loops is another shortcoming in SPSW due to the repeated shear buckling occurring in infill steel panel. An innovative Buckling-Restrained Steel Plate shear Wall (BR-SPSW), which adds R.C. cover plates on both sides of the infill panel, was presented and studied. The R.C. cover plates can prevent the infill panel from buckling, thus to mitigate all the disadvantages of SPSW referred to above. Finite element method is employed to investigate the static and hysteretic behavior of the BR-SPSW. Analysis results show that the elastic lateral stiffness and energy dissipating capacity are improved significantly, and the BR-SPSW system can be applied in high-rise buildings especially in seismic zones to resist lateral forces induced by wind and earthquake. Formulae for determining the elastic lateral stiffness and the ultimate shear capacity are proposed, which can be conveniently used in the preliminary design of BR-SPSW system. |
