摘　　要：介绍了210m高的钢筋混凝土烟囱动力特性的测试成果和横向共振的研究,并且以实测数据首次提出了钢筋混凝土高烟囱发生第Ⅱ振型横向共振的可能性,还就高振型横向共振的风洞实验和烟囱规范的修订提出了建议。This article places emphasis on investigating the measured dynamic characteristics and cross - wind resonance on the reinforced concrete chimney. Not only has the 1st vibratory mode of cross - wind resonance been calculated, but with actual measured data the research of the 2nd vibratory mode has been firstly put forward in this thesis. Furthermore, propositions on wind tunnel test of higher modes and the reuision of Chimney Norms have also been represented.
