WebSolution: Length of steel bar = Total length + over-lap length Length of steel bar = L + 50D 1. Length of bar, if dia of bar = 12mm 12mm = 0.012m (12/1000 = 0.012) = L + 50D = 6.0m + 50 x 0.012m = 6.60m 2. Length of bar, if dia of bar = 16mm 16mm = 0.016m (16/1000 = 0.016) = L + 50D = 6.0m + 50 x 0.016m = 6.80m 3.
