Abstract
Abstract - The performance of reinforced c oncrete (R.C) girder bridge decks is significantly influenced by geometric configurations, among which the skew angle plays a critical role. Skewed bridges are commonly employed to accommodate site constraints, road alignment, and river crossings, but they introduce complex stress distributions, torsional effects, and differential deflections compared to straight bridges. This study investigates the effect of varying skew angles on the structural behavior of R.C girder bridge decks through detailed analysis using finite element modeling. Key performance parameters, including bending moments, shear forces, deflection profiles, and load distribution patterns, are evaluated for different skew angles. The results reveal that as the skew angle increases, stress concentrations and torsional effects become more pronounced, influencing the overall load-carrying capacity and serviceability of the deck. The findings provide critical insights for bridge designers and engineers, enabling optimized design strategies to ensure safety, durability, and cost-effectiveness in skewed R.C girder bridge structures.
