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 …
