摘要
对一4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25%。
Shaking table tests of a four story frame building model with or without tuned mass damper (TMD) are completed,and the test results show that this technique certainly has the earthquake reduction effect. The TMD method is applied to an existing seven story frame building, in which one new story of the frame is added on the top of the building as a ”TMD”. The base shear force of the rehabilited building can be decreased about 30% by the technique.
