Dynamic assessment of PSC bridge structures under moving vehicular loads

This study presents a novel method of extracting the damage information from the response of a bridge induced by operating vehicles. The results also show that operating vehicle loads can be utilised to reduce the number of sensors. It has the potential of detecting damage using vehicle response of highway bridges with small numbers of sensors and without interrupting traffic flow. Finally, the load bearing capacities of a real bridge are predicted by using finite element model updating
