What is Shear Key Performance in Precast Bridges about?

This document presents an experimental study on the shear behavior of joints in precast concrete segmental bridges, focusing on different types of shear keys and joint configurations. Twelve full-scale specimens were tested to evaluate crack development, failure modes, shear slip, and shear capacities, revealing that steel shear keys outperform concrete keys in stiffness and shear capacity. The findings indicate that double-key configurations significantly enhance shear capacity, and steel shear key joints
