The analytic results indicate that after using base seismic isolated technology,the natural period of structure with seismic isolation foundation can be extended to avoid the principal period of the ground and the earthquake energy is efficiently consumed by the deformation of seismi.
分析结果表明:采用基础隔震技术后,钢桁架结构通过延长自身的自振周期避开了地震的卓越周期,同时依靠隔震支座的变形耗能,有效地减少了输入到结构中的地震能量,这就降低了上部结构的地震响应,使大部分构件处于弹性工作阶段,从而达到保护主体结构的目的。
