Horizontal shear force for different arrangements of coupling bars in precast concrete slab with and without steel fibre

In precast concrete slab, the coupling bars and in-situ concrete act as the precast slab panel connection. The design of coupling bars based on Eurocode 2 must be able to resist the horizontal shear force and the U-loop bar must also be design to carry this force. The placing of coupling bars as the...
