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.
