Bridges play a crucial role in modern transportation infrastructure, facilitating the efficient movement of people and goods across various regions. New and advanced developments are being made in these constructions. A pre-stressed concrete I-girder is a type of bridge structure widely used in civil engineering for spanning various distances. These bridges are designed for heavy loads, such as traffic and are known for their efficiency, durability and cost-effectiveness. This comparative study aims to investigate the effects of two well-known design codes, the Indian Road Congress (IRC) and the American Association of State Highway and Transportation Officials (AASHTO), on the behavior and performance of pre-stressed concrete I-girder bridges. A single-span pre-stressed concrete I-girder bridge is modeled and analyzed using the two standard loading codes, IRC 6: 2000 and AASHTO-LRFD. The modeling and analysis of the pre-stressed concrete I-girder bridge is done in MIDAS CIVIL. The use of MIDAS CIVIL as an advanced tool showcases its efficiency and accuracy in analyzing complex bridge structures, reaffirming its significance in modern engineering practices. The results obtained from the analysis are compared in detail, focusing on critical parameters such as maximum bending moments, shear forces, and torsion.
