内容記述 | This study presents the method to approach flutter derivatives (FDs) of bridge section from simulation method. The more challenging is the application the system identification method to extract FDs from the stochastic vibration technique via simulated buffeting responses for section model. The flow analysis includes the investigation on: the fluctuated wind velocities were simulated from target power spectrum, the buffeting responses of a bridge section model obtained from numerical dynamic solution at different mean wind speeds. Next, the gust responses data has been analysis by the system identification technique in extracting FDs and investigate the difficulties involved in this method are discussed. The time domain analysis of gust response, stochastic system identification is proposed to estimate two degree of freedom systems. Finally, some adverse effects of gust response data on the accuracy of these methods to obtain FDs was discussed and concluded. The result of the study can clarify the effects of turbulence on FDs and further apply to estimate FDs from response of full-scale under buffeting load. | |||||
