The modal identification is significant for the condition assessment of transmission towers. However, effect excitation patterns on has not been adequately investigated full-scale In this study, comprehensive field tests are conducted a tower. An automated Bayesian approach proposed to identify most probable values (MPVs) parameters with posterior coefficient variations (COVs). It found that identified MPVs by different consistent, whereas COVs show differences. uncertainty forced vibration...
Up to date, few studies on the dynamic characteristics analysis and model updating of large-size ultrahigh-voltage (UHV) transmission towers with long cross arms have been conducted due lack onsite measurement data. In this paper, a framework for vibration test–based UHV is proposed using fast Bayesian Fourier transform (FFT) method an interactive optimization approach. The response T-shaped ±800-kV tower achieved by performing ambient test. characteristic parameters (frequencies, damping...
