AbstractIn an effort to determine the nature and size of the response of unusually shaped power station buildings, an investigation of one power station building has been made, both theoretically and experimentally. The dynamic response of the structure to wind excitation has been monitored, analysed and compared with theoretical values obtained from an analysis of a simplified structure. The shapes of pure modes of vibration are consistent with the predicted shapes, and correlation between measured and predicted frequency is better than 10 per cent. Damping measurements from the experimental study are included where the signal/noise ratio permitted, and these were found to be in a range that is consistent with values found in other types of steel construction.
