配筋砌体摩擦摆隔震结构地震响应分析

摘要

In view of the restrictivity, revertibility and stability of the friction pendulum, this study makes a comparison upon the acceleration and relative displacement between the original and the isolation structure with numerical analogy method in order to analyze the seismic responses of reinforced concrete masonry structures before and after using the friction pendulum. The result shows that the friction pendulum isolation structure improves the dynamic response of reinforced concrete masonry structures, greatly reduces the seismic responses and achieves distinct isolation effects.%摩擦摆具有较强的限、复位能力和良好的稳定性，为了研究配筋砌体结构采用摩擦摆隔震前、后的地震响应，采用数值模拟方法，对原结构和隔震结构各层的加速度和相对位移进行对比．结果表明，采用摩擦摆隔震结构能够改善配筋砌体结构的动力特性，使地震响应大幅降低，隔震效果明显．
