        abstract = {This study investigates the thermal behavior of a double-cell concrete box girder bridge segment under temperature gradients as specified in IRC:SP:6 using ABAQUS finite element analysis. A three-dimensional finite element model was developed with appropriate material properties, boundary conditions, and thermal loading to simulate real bridge conditions. The temperature gradient applied across the girder depth caused non-uniform thermal expansion, leading to thermal stresses and structural deformation. The analysis evaluated temperature distribution, Von Mises stress, principal stress, strain, and displacement within the girder segment. Results showed that the top slab experienced the highest temperature due to thermal exposure, while the bottom slab remained comparatively cooler. This differential heating created thermal curvature and significant stress concentrations at the web-slab junctions and bottom flange regions. The maximum thermal stress observed was within the allowable range for concrete, while displacement remained within serviceable limits. Manual calculations were also performed to validate the numerical simulation results. The comparison confirmed the reliability of the finite element analysis approach. The study highlights the importance of considering thermal loads in bridge design to prevent cracking and serviceability issues. Thermal effects significantly influence the durability and long-term structural performance of box girder bridges. The findings provide useful insights for improving thermal stress consideration in practical bridge engineering design.},
