【 摘 要 】

Results of an experimental study related to flutter phenomenon are presented in the paper. Two cross-sections are considered: a rectangular cross-section and a typical symmetric bridge cross-section. Stationary coefficients and instationary flutter derivatives are determined by means of forced vibration tests. The identification technique is presented in detail. Pressure measurements at the centre of the bridge cross-section are also performed. Main wind flow patterns are analysed based on pressure distribution data.
