abstract = {This study aims to evaluate and compare the structural performance of underpass bridges subjected to both vehicular and earthquake loading conditions. Underpass bridges are vital infrastructural components that must withstand diverse load combinations to ensure safety and serviceability. The research involves the calculation of base shear using the seismic coefficient method and the determination of the fundamental time period in accordance with IS 1893:2016. Vehicular loads are applied as per relevant design codes to simulate real traffic conditions, while seismic loads are incorporated using dynamic analysis methods to capture the bridge’s response under earthquake excitations. The comparative analysis focuses on key structural parameters such as displacement, bending moment, shear force, axial force, and stress distribution. Through this approach, the study identifies the variations in performance under static and dynamic conditions, providing insights into the most critical load effects governing bridge design. The outcomes of this research are expected to assist in improving the seismic resilience and overall structural efficiency of underpass bridges.},
