A Comparative Study on The Effects of Moving Loads on A Reinforced Concrete Deck Bridge Under IRC Class A And AASHTO HS-20 Loadings

This thesis presents a comparative study on the effects of moving loads on a reinforced concrete deck bridge, examining two distinct loading standards, namely IRC Class A and AASHTO HS-20. The study's primary objectives were to evaluate the structural behavior, assess the performance, and compare the stresses and deformations experienced by the bridge under both loading conditions. Additionally, the research aimed to analyze the safety implications and identify potential vulnerabilities for each loading scenario while investigating critical points influenced differently by IRC Class A and AASHTO HS-20 loadings. The investigation involved analyzing various parameters such as bending moment, deflection, stress, torsional moment, and shear force in the bridge structure. conclusions offer valuable insights into the structural behavior and performance of steel girder deck bridges under various loading conditions and deck thicknesses. The findings can serve as essential guidelines for bridge design and optimization, ensuring the safety, durability, and efficient performance of the bridge structure. Engineers and designers can leverage this research to make informed decisions when selecting appropriate loading standards, ultimately contributing to the overall improvement of bridge infrastructure.
