| 摘 要： | 本文进行了合肥电视塔风振响应分析，探讨了电视塔人体舒适度设计准则。计算表明，电视塔上塔楼的加速度响应大大超出了容许的最大加速度限值。因此，利用塔上60t重的生活、消防用水箱作为调频质量阻尼器(TMD)。通过在频域内大量的TMD参数研究，确定TMD的优化参数。研究结果表明，具有最优参数TMD可以显著提高电视塔的人体舒适度性能，上塔楼的加速度响应下降了49%。在此基础上，本文提出了TMD优化参数的选择路线，结合受控和未控结构的响应比与频率比和TMD阻尼比的关系曲线，采用图解法确定了满足减振要求的TMD优化参数。 |

| Abstract: | Wind-induced response analysis of Hefei TV Tower of 339m high is performed and the serviceability design criterion of human comfort is discussed. It is found that the acceleration response of the upper turret of the tower is much larger than the allowable acceleration of human comfort. Therefore, the water tank of 60 tonnes on the tower which is used for daily water supply and fire protection of the tower is designed as a tuned mass damper in addition to its original functions. After extensive parametric studies in frequency domain, the optimal design parameters of tuned mass damper are determined. With the optimal tuned mass damper installed, the serviceability performance of the tower is improved significantly. Especially, the acceleration response of the upper turret is reduced by as mach as 49%. A graphical approach of selecting the optimal TMD parameters is provided. |
