SEISMIC PERFORMANCE OF PREFABRICATED HIGH STRENGTH STEEL PLATE SHEAR WALL WITH ANNULAR DAMPERS

  • 摘要: 钢板剪力墙因具有良好的抗震性能被大量应用到高层建筑和高烈度区域。为解决装配式钢板剪力墙滞回曲线捏缩、平面外屈曲问题,该文提出一种带环形阻尼器的装配式高强钢板剪力墙。针对该装配式高强钢板剪力墙,变化高厚比和钢材牌号对其进行拟静力荷载作用下抗震性能有限元和试验研究,分析破坏模式、滞回曲线、骨架曲线、刚度退化、耗能性能和延性。研究结果表明:该装配式高强钢板剪力墙内嵌板环形阻尼器和边界连接板带屈服破坏,其他构件完好;滞回曲线饱满,位移延性系数在5.7~8.7,抗震性能良好;提出的抗剪承载力计算公式简单明了、概念明确,与有限元模拟和试验吻合良好。

     

    Abstract: Steel plate shear walls have been widely adopted in high-rise buildings and high intensity areas due to their good seismic performance. In order to avoid hysteretic curve pinching and buckling of prefabricated steel plate shear wall, a prefabricated high-strength steel plate shear wall with annular dampers is proposed. Both finite element analysis and experiments under low cyclic loading were carried out by changing the ratio of height to thickness and the steel grade. The failure mode, hysteresis curves, skeleton curves, stiffness degenerations, energy dissipation and ductility were analyzed. The results show that the annular dampers of the inner panel and the boundary connecting plate belts experience yield failure under low cyclic loading, while the other components remain intact. The hysteresis curves are full, and the displacement ductility coefficients are within the range from 5.7 to 8.7. Thus the prefabricated high-strength steel plate shear wall exhibits satisfying seismic performance. The proposed design formulas are simple with clear concept, which agree well with the finite element calculation and test results.
