1. For the rectangular beam shown here, calculate the development lengths of top No. 7 bars and bottom No. 9 bars. No. 4 bars are used for stirrups. The spacing of stirrups is 6 in. The clear side cover depth is 1.5 inch. (Clear cover depth means the distance from the beam face to the outer surface of a bar). Normalweight concrete is used.
