隔震板柱结构—基础—地基相互作用地震反应分析

Earthquake Response Analysis of Slab-Column Structure-Foundation-Soil Interaction

对广州地区一例地基—基础—隔震板柱结构动力相互作用体系进行了计算分析。通过与常规设计方法及非隔震体系的比较,研究了该体系地震反应的变化规律,并分析了阻尼比、地基土特性、基础刚度、基础型式、基础埋深、土体深度、上部结构刚度和地震波等因素对相互作用体系动力特性及地震反应的影响。

Exemplified by an engineering building of Guangzhou, China, the seismic response of slab-column structure-raft foundation-soil interaction system was analysed using 3-D finite element method. Through comparing the interaction results with non-interaction results of the system, the varying rules of dynamic response was studied, and the influences of some factors on the system＇s dynamic characteristic and seismic responses, such as the damping ratio, soil property, the rigidity and type of foundation, the buried depth of foundation, the rigidity of structure and the seismic wave were discussed.
