Summary

In the realm of bridge construction, Reinforced Concrete (RCC) girders stand as critical structural components, bearing the weight of the bridge deck while efficiently channelling diverse loads to the substructure. Renowned for their resilience, extended service life, and cost-effectiveness in bridge engineering, these girders form the cornerstone of our comprehensive investigation. Our study revolves around the meticulous development of three-dimensional finite element models for simply supported girders, embracing different cross-sectional shapes (Rectangular, T-section, and I-sections) within the ANSYS software platform. These meticulously designed models harness both solid and shell elements available in the ANSYS library. Our analysis encompasses a spectrum of concrete grades and diverse loading scenarios, all while maintaining a uniform temperature. Through a meticulous exploration of physical behaviours, including stress, strain, and deformation, we engage in a rigorous comparative assessment of these distinct models.

Our findings distinctly showcase that the I-section girder outperforms the other geometries in terms of stress and strain values. On the other hand, the T-section girder emerges as exceptional in deformation characteristics. Notably, our study highlights the advantageous outcomes achieved through the application of high-strength concrete grades. This valuable insight equips structural engineers and designers with essential guidance for selecting the most suitable cross-sectional shapes and concrete grades, meticulously tailored to the unique demands of specific applications.
