摘　　要：分别输入El-Centro波(N-S)、Taft波和人工合成的合肥波,通过Newmark-β法计算了合肥电视塔的地震响应。最后利用塔上60t生活和消防水箱作为调频质量阻尼器(TMD),通过大量时程分析来对TMD参数进行优化分析,确定了3条地震波作用下TMD的最优参数。TMD的参数分析结果表明,采用最优参数的TMD使得电视塔的地震响应大大降低。The seismic response of Hefei TV Tower under the E1-Centro ,Taft and simulated earthquake wave of Hefei excitations are performed using the Newmark-β method, Finally, the water tank of 60 tones on the tower which is used for daily water supply and fire protection of the tower is designed as a tuned mass damper. After extensive parametric studies in time-history analysis, the optimal design parameters of Tuned Mass Damper are determined. The parameter analysis of TMD shows that the seismio responses of the tower are decreased greatly with the optimal parameters of TMD.
