Max Dia Of Steel Bars In Slab

Main bars of 12 mm and cross bars of 10 mm are applied in the slab.

Max dia of steel bars in slab. The presence of re bar or wwf in a slab on grade increas es confidence in the ability of. Length of main bar 2960 0 42 x 88 24 2973 mm or 2 97 m. Minimum reinforcement is 0 12 for hysd bars and 0 15 for mild steel bars. The minimum ratio of required reinforcement is.

Thickened edges add more restraint to drying shrinkage and cost more. The maximum diameter of bar used in slab should not exceed 1 8 of the total thickness of slab. F min 0 0025. 6 mm 8 mm 10 mm 12mm and 16mm.

Find length of distribution bar clear span ly 2 x development length ld 5000 2 x 40 x 8 5640 mm or 5 64 m. This allows the de signer to maintain a constant slab depth without thickening at joints or edges. Suppose the steel bars with diameter 12 mm main bars in horizontal direction and 10 mm cross bars are used in the slab in vertical direction. Maximum spacing of main bar is restricted to 3 times effective depth or 300 mm whichever is less.

F min 0 002 for f y 40 000 psi. Suppose there is one slab with dimension 1 m x 1 m. The temperature reinforcement shall not be less than inch at nine 9 inch center to center. The main bars are used in short span and cross bars are used in long span.

The diameter of bar generally used in slabs are. Reinforcing steel gives slabs on grade adequate strength at the joints. F min 0 0015. D slab thickness 2 side clear cover dia of bar 150 50 12 88 mm.
