| 摘 要： | 形状记忆合金(简称SMA)是一种智能材料,具有良好的耗能能力,在建筑结构的振动控制中具有广阔的应用前景。主要介绍了SMA材料的特性,并提出其一种本构模型,对SMA拉索被动控制的原理和方法作了分析说明。实验结果表明该本构模型能减小地震能量向上部结构的传递,从而降低上部结构地震响应。

| Abstract: | Shape memory alloy(SMA) is a kind of intelligent material with good capacity of dissipating energy,and will have a wide applicable prospect in vibration control of architectures.The SMA material characteristics were mainly described with a simplified constitutive model proposed.The principle and method of the passive control to make simple elucidation to the SMA cable were also stated and analyzed.The results of experiment expatiated that the simplified constitutive model can decrease the transmission of the earthquake energy up to the superstructure,thus the response to the earthquake in superstructure can be reduced. |
