Abstract

Making use of long-term monitoring data, this study aims to characterize the correlation between wind speed and wind-induced displacement response of the Tsing Ma Bridge in Hong Kong. Wind data recorded by anemometers during typhoons are firstly analyzed. Valid 10-min mean wind speed data higher than a threshold value are chosen and the corresponding frequency distribution of wind directions is determined. Wind-induced displacement responses measured by GPS are processed in a similar way. Then the statistical relationships between wind speed and wind-induced displacement response are explored for different bridge sections and different wind directions, which are greatly helpful for wind-resistant performance assessment of the bridge. With the formulated correlation pattern, the displacement response under design maximum wind speed can be predicted and compared with the design allowable values for design validation.
