摘要
介绍了形状记忆合金(SMA)的基本特性和本构模型,并通过建立被动控制高层建筑结构地震响应的运动方程,探讨其控制原理和方法,通过与无控方案和设置了传统钢拉索的方案进行比较,结果表明形状记忆合金具有明显的阻尼特性,可以显著地抑制结构的地震反应。
This paper introduces the basic characteristic and the constitutive model of Shape Memory Alloy(SMA),and set up its seismic response motion equation of tall building structures using passive control device and explores its principle and methods of passive control.It compare a non-control program and a program with traditional steel cables to a program.The result indicates that SMA has obvious damping,the seismic response of structure can be reduced significantly.
