基于形状记忆合金X形板阻尼器的结构振动控制
|
摘要
超弹性形状记忆合金X形板阻尼器具有良好的耗能及复位功能.建立了形状记忆合金X形板的分段线性化恢复力模型,并在此基础上提出了该阻尼器控制下的框架结构振动响应分析方法.数值计算了一装有该阻尼器的单层剪切型钢框架的地震响应,表明该阻尼器可以有效抑制结构的震动,并分析了阻尼器特征参数对结构减震的影响.
uperelastic shape memory alloy(SMA) X type plate damper has energy dissipation and re-centering capa-bilities.The damper's piecewise linear hysteretic model is set up,and the dynamic response analysis of a single degree of freedom structure with the SMA damper subjected to earthquakes is put forward.Numerical simulations show that the SMA damper can reduce the seismic response of the structure effectively,and the influences of damper's parameters on the response of the structure are studied.
