Shear strength of match cast dry joints of precast concrete segmental bridges: proposal for Eurocode 2

This paper discusses a study on the performance of concrete segmental bridges with shear keys, focusing on the shear behaviour of castellated dry joints under ultimate limit state conditions. The widely varying formulation used to evaluate joint shear strength were compiled, along with the experimental results published in the literature on the subject. The various approaches were evaluated by comparing their predictions of ultimate joint strength to published empirical findings. The formula giving the best prediction was adapted to the safety factor provisions set out in Eurocode 2.
