In general, moving vehicles generate continuous and repetitive strain of energy on bridges. The strain energy can convert to electric energy due to its piezoelectric element. However, some factors should be considered in order to reasonably assess the feasibility such as load distribution applied on bridges and the relationship of strains generated according to loads. This study was carried out to estimate the generated voltage when piezoelectric elements were installed to a bridge. A steel-concrete composite specimen was fabricated and loads were applied, considering vehicle load-effects. As a result, the voltage generated in the element was evaluated and compared with the analysis equation of the piezoelectric effect.
