Abstract
Long-term monitoring data of bridge deck accelerations and wind velocities from the Hardanger Bridge were used here to investigate the relationship between the wind characteristics and the bridge response. The bridge, as well as the extensive monitoring system installed on it, is introduced. The wind velocities and bridge deck accelerations were recorded on several locations along the bridge span using 20 accelerometers and 9 anemometers. The lateral, vertical and torsional accelerations of the bridge deck are presented in the form of buffeting curves. Response surface methodology (RSM) was employed to elaborate on the significant variability observed in response components. Using wind field statistics as predictor variables in the analyses, the variability in response was attributed to the variability in the wind field. The effect of wind-related variables on the response and their interactions are presented using surface plots.
