摘要
通过对土建结构进行动态性能分析,提出在结构上设置附带阻尼器的双簧摆来减小结构的地震响应。用复模态迭加法对一算例在4条不同地震波分别作用下的时程响应计算表明,该方法可显著减小并衰减结构的地震响应。
Based on the analysis of dynamical behaviours of building structures and properties of the seismic force on buildings, this article presents a device-pendulum with spring and added damper-for reducing the structural response to earthquake, An example of a structure subjected to four earthquake waves respectively shows that the device is effective.
