Bridges are ensuring the smooth flow of goods and people. The seismic performance of bridges, especially those with unique geometries, such as T-beam bridges with zero skew angles, is paramount in earthquake-prone regions. This project comprehensively analyses a T-beam bridge with a 10⁰ to 50⁰ skew angle. The response of T-beam bridges to varying skew angles is a critical area of study in structural engineering, as skewed bridges are standard in modern infrastructure due to geometric and site constraints. This research investigates the impact of different skew angles on the structural performance of T-beam bridges, focusing on parameters such as bending moments, shear forces, deflections, and stress distribution. The study uses finite element analysis and empirical data to reveal how increasing skew angles affect T-beam bridges' load-carrying capacity and deformation behaviour. The study encompasses several key aspects: Detailed documentation of the bridge's geometry, materials used, and construction techniques employed in the T-beam Bridge under consideration and the development of a finite element model to represent the T-beam Bridge accurately, comparison by varying the skew angles and applying various seismic ground motion records to simulate the bridge's response under earthquake-induced loading and assess the bridge's performance using performance metrics such as moment, shear and torsion levels.
