多层异型柱框架结构隔震性能试验研究

本文对一栋比例为1:6的6层基础隔震异型柱框架结构模型进行了模拟地震振动台试验研究.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,从而使上部结构设计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可降低工程造价的目的.

Experimental Study on the Seismic Isolation Effect of a RC Frame Model with Unusual Columns

Shaking table test research and theoretical analysis on seismic isolation effect of a RC frame model with unusual columns (L or T or+section) is introduced in this paper. The prototype of the model is the first base isolated frame building with unusual columns in Guangzhou, 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 method of earthquake action and dynamic characteristic for regular frame buildings with base isolation can also be used on such kind of structure.
