At the present the use of box girders has been gaining popularity in bridge engineering due to its greater stability, serviceability, economy, aesthetics and structural efficiency. So this research focuses on the study of behavior and structural response, of concrete bridges with curved box-girders subjected to seismic actions to determine by numerical modeling, the nonlinear and seismic response taking into account nonlinear material behavior. This study investigates the potential damage that it could suffer the bridge during earthquakes, 3D numerical models with beam and solid element were developed by using of the FEM of an existing bridge and were carried out analysis step by step and nonlinear. The structure is composed of concrete frame in longitudinal direction, which is formed by rectangular columns of variable section, the requirements of AASHTO, IMT-SCT and CFE-2008 were used. Finally, it is observed from the 4 models that as the radius of curvature of the structure in plan, is more noticeable, the concentration of cracking and crushing of concrete is located in the central segments and piers, respect to the time analysis, the displacement histories are more evident in straight bridge.
