TL;DR: In this article, the authors investigated the vortex-induced vibration of a twin steel box girder suspension bridge with a center span of 1650 m based on field measurements, and they found that the vortex shedding more likely occurs in a low wind speed range of 6-10m/s, with the wind direction nearly perpendicular to the bridge line, and low turbulence intensity.

TL;DR: In this paper, a long-term wind and wind effect monitoring system was created to investigate full-scale wind-induced vibrations of a longspan suspension bridge with a central span of 1650m.

TL;DR: An identification framework based on a restricted Boltzmann machine (RBM) for crack identification and extraction from images containing cracks and complicated background inside steel box girders of bridges and results show that there exists optimal element size.

TL;DR: Wang et al. as discussed by the authors used computer vision technology combining the monitoring information of the weigh-in-motion system (WIM) at one crosssection and the camera along the bridge, a method to identify the spatio-temporal distribution of vehicle loads for long-span bridges is proposed.

TL;DR: In this article, the authors investigated the correlation of wind characteristics monitored on a cable-stayed bridge, where four anemoscopes are respectively distributed at two cross-sections and another anemoscope is installed at the top of the tower.
