摘要
介绍了形状记忆合金(SMA)阻尼器的性能,引入其本构关系,建立其热力学方程。针对所提出的阻尼器及相关参数选择,利用ANSYS进行框架结构中的被动控制模拟。将所得的未加与加入SMA阻尼器下顶层位移进行比较,发现SMA阻尼器可以很好地提高框架结构的抗震性能,并提出进一步研究的方法。
The performance of shape memory Alloy （SMA） damper and its constitutive relation are presented, and its thermodynamic equation is set up. Then, the SMA damper passive control of a frame structure is simulated by ANSYS according to its relative parameter selection. Finally, through comparing the top floor displacement of the frame structure without and with SMA damper, it is shown that the SMA damper can enhance the seismic performance of the frame structure, and the method for next research work is put forward.
