This study mainly focused on the evaluation of the electrical energy generation in a bridge which installed the piezoelectric system. The source of the system would be the vibration of the bridge, which is mainly induced by the traffic load. This study performs analyses on energy generation capacity of a typical one-span steel plate girder bridge, considering the various traffic conditions. Piezoelectric materials are uniformly installed in the u-ribs, crossbeams and the slab. Various parameters such as vehicle headway distances and heavy traffic ratio are considered during the analysis. The results showed that the narrower traffic headway distance induces more energy generation. It also revealed that the higher heavy traffic ratio produces more electricity. Such results indicated that the continually passing heavy traffics may maximize the efficiency of energy generation system. © 2012 Taylor & Francis Group.
