SMA—滚珠隔震支座对框架自振周期影响研究

Study on the natural period of vibration to framework by support with SMA—ball shock insulation

对单榀框架在不安装滚珠隔震支座和安装滚珠隔震支座的情况分别进行了敲击试验,通过分别采集其频谱,探究了滚珠隔震支座对此框架自振周期的影响,从而得出滚珠隔震支座可提高框架结构的抗震性能。

Through the knocking experiment towards single framework under the circumstances of installing and non-installing support with ball shock insulation, collecting the frequency spectrum respectively, investigating the influence of natural vibration period to this framework by sup- port with ball shock insulation, resulted that the support with ball shock insulation could enhance the anti-seismic property to the framework.
