摘要
本文对置于某一超高层建筑顶部的钢质天线抖振响应进行了研究。对两种天线单体方案的抖振性能进行了气动弹性模型试验和理论计算和比较 ,最后分析了天线的鞭稍效应。计算和试验结果为天线结构的分析设计提供了依据。
A research on the buffeting response of two types of steel antennas at the top of a super-high rise building is presented. The two types of aeroelastic antenna models were tested in a wind tunnel and numerical computations were made to theoretically and experimentally investigate the buffeting responses of the antennas. A structural improvement measure for the second type of antenna model was proposed and the model was tested. The whiplash effect of the second type of antenna was numerically analysed. The numerical and experimental results provide the reliable basis for the analysis and design of the structure.
