Slab-girder structures composed of steel girder and reinforced concrete slab are widely used in buildings and bridges in the world. Their advantages are largely based on the composite action through the shear connection between slab and girder. In order to assess the integrity of this kind of structures, numerous vibration-based damage identification methods have been proposed. In this study, a...

Vibration displacements are one of the most significant indicators in health monitoring and condition assessment bridges life cycle. The traditional means, such as contact sensors, have relatively high-cost limited points for displacement measurement bridges. This paper proposes a low-cost non-contact monocular vision system based on KCF algorithm to accurately timely identify vibration A conve...
