摘 要: 对置于某一超高层建筑顶部的钢质天线的抖振响应进行了研究 .首先用随机振动理论计算了天线的抖振响应 ,而后在风洞中对天线的气动弹性模型进行了试验 ,最后还分析了天线的鞭稍效应 . The research of the buffeting response of the steel antenna at the top of one super-high rise building is presented in this paper.Firstly,the random vibration theory is implemented to compute the buffeting response; secondly the aeroelastic model of the antenna has been tested in a wind tunnel.The whiplash effect of antenna is finally numerically analysed.The numerical and experimental results provide the reliable basis for the structure analysis and design.
