Analytical Studies on Shape of Shear Pocket of Full-Depth Precast Slab

Full depth precast concrete bridge deck system can be advantageously to reduce construction time, hence lowering the cost. This system has several significant design and construction component. To connect between the concrete slab and steel girder, precast deck has shear pocket. Post-tensioning tightens the joints and prevents any leakage though the joint. When post-tensioning is applied, stress concentration occurs in the edge of shear pocket. In this study, precast decks using four types of shear pocket is analyzed by F.E.M.
