摘 要: 在平转耦联隔震结构简化体系的基础上,对地震作用下的反应进行了数值时程计算,并对各有关动力参数对地震反应的影响进行了分析研究.结果表明:在上部结构偏心不大的情况下,隔震层偏心距的变化对上部结构的位移和转角的影响不明显.通过合理地调整隔震层的偏心距,结构的底部扭矩可以明显降低. Based on a simplified system of translation-torsion coupling isolated structure,this paper calculated time-history response of the system under earthquake and analyzed the influence of dynamic parameters in seismic response. The results show, when eccentricity of superstructure is small, the effect of eccentricity of isolated floor on the displacement and rotating angle of superstructure is not obvious. And the base torsion is decreased remarkably by rationally adjusting eccentricity of isolated floor.
