摘要
对多层基础隔震偏心结构进行了水平双向地震作用下的时程反应分析,研究了基础隔震偏心结构的平-扭耦联地震反应,并与传统抗震结构进行了对比分析,表明采用基础隔震技术可以有效减小结构的平-扭耦联地震反应,从而保护上部结构及其内部设施.
The lateral-torsional response of the base-isolated asymmetric structures under bilateral ground motions is studied, and the comparing analysis on the response between the base-isolated structure and the fixed-base structure is carried out. It is shown that the lateral-torsional response of the structure can be effectively diminished by adopting the base-isolated technology.
