Reinforcement Lapping | Reinforcing Bar(Rebar) | Concrete ...
If two segments of reinforcing bar (rebar) are coincided to form a constant line of rebar, then lap should be provided. The lap length varies with different factors like the concrete strength, the rebar grade, size, and spacing. The lap is formed to transfer load from one bar to another bar and sustain continuity.

How to Calculate Amount of Rebar | Hunker
Apr 11, 2018· Layout of Rebar for Concrete Slabs. You'll therefore need 14 lengths of rebar. To calculate how many pieces of rebar you'll need for the longitudinal placement, the calculation is the same, except you'll switch latitude for longitude throughout the calculation. In other words, begin by measuring the latitude length of your area.
