摘　　要：以某框架建筑结构为工程背景,以该框架结构为基础分别设计成隔震建筑物和加阻尼器后的减震建筑物,对一般建筑物、隔震建筑物以及加阻尼器后的减震建筑物的地震响应分别进行分析,对加速度时程、楼层平均位移峰值、层间变形峰值、建筑物基底剪力峰值进行对比研究。研究结果表明,对同一个分析模型,地震作用下建筑物加速度峰值中一般建筑物最大,其次是减震建筑物、隔震建筑物;对于建筑物的层间变形,由小到大分别是隔震建筑物、减震建筑物、一般建筑物;地震作用下建筑物的位移中,最大的是隔震建筑物,其次是一般建筑物,最小的是减震建筑物。Taking a practical framework for the in-ternational structural engineering background to the frame structures were designed based on isolation damping buildings Canadian buildings damper after the seismic buildings, isolated buildings and add damper after damping seismic response of buildings were ana-lyzed on the way, the average floor building seismic displacement peak acceleration, vibration isolation of buildings and structures, the interlayer deformation peak, peak base shear building comparison the stud-y. The results show, for the same model, earthquake peak acceleration in the building is the largest building earthquake followed by damping the building, is the smallest isolated buildings, where buildings and seis-mic damping peak acceleration Buildings or less, iso-lation and damping building structures differ quite far;interlayer for building a minimum distortion, isolated buildings, followed by damping the building, is the largest seismic building; building under earthquake displacement thereof, the largest building is isolated, followed by seismic buildings, minimum damping is building.
