摘要:
在常规的摩擦摆支座FPB中引入呈竖向布置的形状记忆合金SMA丝,可形成一种新型隔震支座SMA-FPB。根据先期开展的试件设计方案,利用ABAQUS建立了上述SMA-FPB的精细化有限元模型。在此基础上,进行了该新型SMA-FPB隔震装置在往复加载下的滞回性能数值模拟,将其与数值模拟结果进行了对比,从而验证了所建模型的准确性。基于上述数值模型,考察了SMA丝数量、摩擦系数以及滑移面曲率半径对此隔震装置滞回性能的影响。研究结果表明,随SMA丝数量和摩擦系数的变化,SMA-FPB的等效刚度、单位循环耗能以及等效阻尼均产生了较大幅度的增加和减小,而滑动面曲率半径的变化对SMA-FPB滞回性能影响较小。
