【摘要】 对大底盘多塔隔震结构采用理想化质点系模型进行了分析,揭示了大底盘多塔隔震结构地震响应的相关特点。通过对一采用基础隔震的大底盘多塔结构工程实例的设计方法进行探讨,得出大底盘多塔隔震结构设计时应该根据各塔楼的特性并采用多种计算模型综合比较进行设计,同时应尽量减小隔震层刚度,选择最优隔震层屈服力。更多还原

【Abstract】 The seismic isolation multi-tower structure with enlarged base was analyzed using ideal particle system model to reveal relevant characteristics of seismic response of the structure. The design method of a practical project of the multitower structure with enlarged base and seismic isolation base was discussed. It’s concluded that several analysis models should be taken into account to compare and design according to structural characteristics of different towers for the structure. And the stiffness of isolated story should be reduced as possible and an optimized yield force should be selected.更多还原
