This lowers the transfer of stress on portions of the concrete and for that reason helps you to minimalize the probability of cracking developing because of temperature fluctuations.
The dimensions of your dowel bar really should be picked based on the size and kind of concrete slab, in addition to the traffic masses Will probably be subjected to. On the whole, bigger dowel bars are proposed for heavier Dowel Bar targeted traffic loads, because they can offer higher load-bearing ability.
The spacing requirement typically depends upon components including the beam's Proportions, the grade of metal reinforcement, as well as loading conditions. Here is a basic method to determine the volume of rebars:
