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。
Anti-buckling steel plate shear wall is a new high-rise building steel structure of anti-side members. The lateral displacement stiffness, shear ultimate bearing capacity and hysteretic behavior of buckling-restrained steel plate shear wall under horizontal load are numerically studied. The anti-buckling limit of anti-buckling steel plate wall Bearing capacity and elastic side stiffness calculation formula for the design of reference. The analysis of hysteretic behavior of anti-buckling steel plate wall and ordinary steel plate wall shows that anti-buckling steel plate wall can significantly improve the phenomenon of pinching of the hysteretic curve of ordinary steel plate wall, showing stronger ductility and stable energy dissipation capacity It is very suitable for the anti-side force system in the area of high seismic fortification.
