摘要

摘要:针对实际高层高耸结构在设置TMD控制装置时,存在空间位置有限、TMD行程受限的问题,进行了带限位TMD的抗风动力可靠度研究。首先,采用虚拟激励法计算复杂高耸结构—TMD体系在脉动风荷载下的随机风振响应;然后,基于随机振动的首次超越破坏准则,研究TMD装置在容许行程范围内不同重现期风荷载下的动力可靠度。并以国内在建的第一高塔-广州新电视塔为工程算例,验证了该研究在实际设计中所具有的重大工程意义。

Abstract

Abstract: Considering insufficient space in installing TMD at high-rise tower structure in practical engineering application, a study on wind-resistant dynamic reliability of TMD with limited spacing is developed. Firstly, the wind-induced stochastic responses of the high-rise tower structure is calculated by using pseudo excitation method. Further, the wind-resistant dynamic reliability of TMD shock absorber within the acceptable level of TMD stroke is investigated for different returning periods wind loads, based on First Excursion Failure Criterion of random vibration. New Guangzhou TV Tower, which is the highest engineering structure in China, is employed as a numeric example herein. Results show that this study is of great engineering significance.
