Abstract:
The general purpose of reinforcing bars in slabs-on-ground is to control crack widths at the top surface of a slab. As the amount of reinforcement increases across the joint, the probability of out-of-joint cracking increases, as tighter cracks may occur at closer spacing than the joints. The Q&A provides some guidance on the amount of reinforcement crossing the joint and its role.
