形状记忆合金以其优异的超弹性和适度的耗能能力在土木工程领域引起了广泛的关注。目前，已经开发出形状记忆合金电缆来满足实际应用的大尺寸需求。本文使用 OpenSees 对形状记忆合金缆索支撑的自定心耗能钢框架 (SMA-SCEB) 的地震响应进行了数值研究。首先对形状记忆合金电缆的机械性能进行了实验研究，并与传统的形状记忆合金线/棒进行了比较。实验结果表明形状记忆合金电缆具有优异的超弹性性能。然后提出了 SMA-SCEB 装置，并进行准静态循环加载测试以评估其迟滞行为。 SMA-SCEB装置安装在钢框架结构中，以增强其抗震性能。进行非线性动力分析以检查其地震响应。为了进行比较，还研究了预张拉玄武岩纤维增强聚合物缆索自定心耗能支撑（BFRP-SCEB）的性能。数值结果表明，自定心耗能支撑可以显着降低结构的残余漂移率。特别是，配备SMA-SCEB的钢框架结构比配备BFRP-SCEB的钢框架结构承受更小的峰值加速度。
Shape memory alloys have attracted a great deal of attention in civil engineering due to their excellent super elastic and moderate energy dissipating capabilities. At present, the shape memory alloy cables have been developed to meet the large size demand for practical applications. This article carries out numerical studies on the seismic responses of the steel frame with self-centering energy dissipation braced on shape memory alloy cables (SMA-SCEB) using OpenSees. The mechanical properties of the shape memory alloy cables were experimentally investigated first and compared to the traditional shape memory alloy wires/bars. Experimental results show the excellent super-elastic property of the shape memory alloy cables. A SMA-SCEB device is then proposed, and quasi-static cyclic loading tests are performed to evaluate its hysteretic behavior. The SMA-SCEB device is installed in the steel frame structure to enhance its seismic performances. Nonlinear dynamic analyses are carried out to examine its seismic responses. For comparison, the performance of self-centering energy dissipation brace with pre-tensioned basalt fiber–reinforced polymer cables (BFRP-SCEB) is also studied. Numerical results demonstrate that the self-centering energy dissipation brace can significantly reduce the residual drift ratio of the structure. In particular, the steel frame structure equipped with SMA-SCEBs suffers smaller peak acceleration than the one with the BFRP-SCEBs.
