Bridges have undeniable importance at different parts of urban areas. In this study the influence of various forms of bridge decks, flexible joints and other elements of concrete bridges with diverse size have investigated, because of high rate of popularity of concrete bridges in construction project. Due to the significance of plastics in analyzing the seismic response of bridges, finite element model is chosen in this project. In the present study, two types of hinges, including fiber hinge and the force moment interactive hinge (PMM), have been selected to indicate the ductility of the columns in the lower and upper regions of the abutments and in the length of the plastic hinge. A huge decrease can be seen in dissipation of energy through pier, by interpreting the data of designed models and effect of dedicated earthquake force. Therefore, to reach better efficiency, it is suggested strengthening the seismic behavior of traditional bridges. To assess short bridges, roller model is not a reliable way to get accurate results, but in long bridges with the length of more than 95m, a simple model can be set to evaluate bridge response.
