摘要
为了将SMA用于结构减隔震,对剪刀型SMA阻尼器进行了优化设计,对其计算模型进行了简化和分析.用有限元模拟方法计算了装有SMA剪刀型阻尼器的9层钢框架结构,在多遇和罕遇地震下的地震响应;探索了阻尼器角度参数对减震效果的影响.结果表明,剪刀型SMA阻尼器具有良好的减震效果,适当调整角度参数可满足不同结构的抗震设计要求.
In order to use SMA to control the seismic response of structure,SMA damper was optimal designed in this paper,and calculation model for the ferfex fixing organization was introduced.The damping effects of 9-floor steel frame structure with forfex-type SMA damper under normal and uncommon earthquake were simulated and analyzed;the affect of angle parameter on damper performances was discussed.Analyze results indicated that the forfex-type SMA damper has favorable damping effect,and can meet the seismic desi...
