摘　　要：对一栋１：６比例的５层基础隔震异型柱框架结构模型进行了地震模拟振动台试验研究。试验与理论分析表明，对这种轻型框架结构体系使用基础隔震技术，可以大大减小结构的地震反应，从而使上部结构可参照基础隔震普通框架结构的设计方法进行内力计算，达到既提高抗震性能，又降低工程造价的目的。Earthquake simulation shaking table test and theoretical analysis on seismic isolation effect of a model of RC frame with special-shaped columns(“L”,and cross shaped section) are introduced in this paper.The prototype of the model is the first base isolation frame building with special shaped columns at Guangzhou City,China,constructed in 1995.It is proved that the seismic responses of this structural system could be greatly reduced by means of base isolation techniques.The calculation of earthquake response and dynamic characteristic analysing method for regular frame buildings with base isolation can also be used to such kind of structure.
