Analyze Effect Of Skew Angle On Performance of R.C Girder Bridge Deck
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 …

A Review: Performance analysis of overlapping shear keys in box girder bridges using finite element based software
Abstract: Abstract - Box girder bridges are widely used for long-span constructions due to their high strength-to-weight ratio and structural efficiency. A fundamental component in these bridges is the shear key which allows for effective transfer of loads between bridge segments and upholds the overall structural performance through the different load cases. Overlapping shear keys are becoming increasingly popular because they greatly enhance inter-segment connections, which decrease relative displacements. This paper …
