摘　　要：对某个6层框架结构进行了有、无TMD结构的振动台对比试验,验证了TMD对多层结构具有一定的减震效果。应用TMD方法对某个7层框架结构进行了“加层减震”改造,分析表明,改造后的建筑与改造前相比,结构的底部剪力下降了约30％。Shaking table test research of a six story frame building model with or without tuned mass damper (TMD) are completed and it shows that for the former scheme certain seismic reduction effect are realized. An application of the TMD method in an existing seven story frame building is put forward, in which one story of frame is added on the top of the building as a 'TMD' . Calculation and analysis indicate that the base shear force of the improved building can be decreased about 30%.
