摘要

研究了由滚轴和橡胶隔震支座构成的组合体系的隔震性能。将这种隔震体系安装在一个5层钢框架模型上,滚轴和橡胶隔震支座各承担一半竖向荷载。在振动台试验中,分别输入相当于8度设防烈度的El-Centro、Taft、Hachinohe、Tianjin地震波,测得各层X、Y两个方向的加速度反应和层间位移反应,试验表明,该组合体系具有明显的隔震效果。最后,用ANSYS有限元程序对该体系的隔震效果进行了分析。
In this paper,the effect of the combinatorial isolation system made up of rollers and lead rubber bearing is researched. A five-story steel frame model is fixed with this system in which rollers and lead rubber bearing take on half of the vertical load respectively. During the shaking table test,the earthquake waves of seismic fortification of 8 degree such as El-Centro,Taft,Hachinohe and Tianjin are input in turns. Acceleration response of every floor and shift displacement are acquired. The isolation efficiency is testified by the test result. At last,ANSYS is used to analyze the isolation efficiency of this system.
