摘要
将SMA弹簧—摩擦支座(SFB)用于多层混凝土框架结构的基础隔震,利用SAP2000有限元软件模拟了SFB隔震结构和无控结构的地震响应,由研究结果可见,SFB能够有效保护结构免遭地震损害,并可提供良好的支座复位性能与限位能力。
In this paper, the SMA Spring-Friction Bearing（SFB） is applied to base isolation system for multi-story concrete frame structure. Nonlinear time history analyses of the isolated and non-isolated structures are performed by using SAP2000 software. The numerical results show that the SFB can effectively protect the frame structure from the damage of earthquake. It is also revealed that the SFB has excellent bearing dis- placement reduction performance and re-centering capability.
