Abstract: This study presents a comprehensive methodology for the design and analysis of bridge retaining walls and abutments subjected to Indian Roads Congress (IRC) bridge loading standards, specifically focusing on IRC:6. The structural integrity of these components is critical for the overall stability of bridge systems, necessitating precise load estimation and modeling. The research integrates computational tools, utilizing STAAD.Pro for finite element modeling and structural analysis, and AutoCAD for detailed engineering drafting and reinforcement layout.The analysis workflow begins with the derivation of superstructure reactions (dead, live, and impact loads) according to IRC:6 provisions, coupled with geotechnical lateral earth pressures. Seismic effects are evaluated using the Mononobe-Okabe analytical method, supplemented by finite element verification to account for non-linear soil- structure interaction. In STAAD.Pro, the wall and connected wing walls are modeled using four-noded plate elements to capture complex bending, shear, and torsional behaviors. Results from the analysis—including moment and shear envelopes—are used to optimize reinforcement detailing. The study concludes with the generation of high-precision construction drawings in AutoCAD, ensuring adherence to code-specified anchorage and drainage requirements. This integrated approach ensures a robust, code-compliant design that balances structural safety with computational efficiency.
