| 摘 要： | 通过形状记忆合金（SMA）材料的超弹性性能试验确定了SMA材料的各项力学性能参数，根据结构的振动控制理论，针对框架结构剪切型变形的特点，建立了SMA拉索对结构进行被动控制的运动方程。然后针对不同的控制方案，应用ANSYS有限元程序，仿真分析了多层钢结构模型在地震激励下的高度非线性动力时程响应，研究了SMA被动拉索的控制效果。

| Abstract: | Based on the experiment for shape memory alloys＇（SMA） super elastic behavior, mechanical parameters of SMA in normal temperature are confirmed. According to structural vibration control theory and shearing deformation property of frames, a passive con- trol equation of structural motion based on SMA tendons is established. Then, to different control methods, ANSYS finite element program is used to simulate the nonlinear time-history response of multistory steel frames under earthquake, and control effect of SMA is studied. |
