Long-term continuous monitoring of the dynamic response of the steel bridge

The dataset contains measurements obtained from strain gauges installed on the upper and lower flanges of the inner girder of the bridge superstructure. The data were collected during both short-term and long-term monitoring periods under normal traffic conditions dominated by heavy lorry crossings. Short-term measurements capture detailed time histories of stress responses induced by vehicle passages across the bridge, including dynamic characteristics of the structure. Long-term monitoring, conducted over approximately 98 days, was used to evaluate the fatigue loading of the structure by determining the number of stress cycles occurring in different amplitude classes. The dataset provides information necessary for fatigue assessment and long-term structural health monitoring of steel bridge structures.
