main bar and distribution bar difference

MAIN BARS IN SLAB:

1. The main reinforcement are to be provided at the shorter span of the slab, because in the shorter span slab facesHigh bending Moment which is known as sagging or positive bending moment.

2. Main reinforcement bars will counter or responsible for taking all the tensile stresses, bending moment (Sagging), and superimposed load (Dead load) which developed at the shorter span of the slabs.

3. Main reinforcement bars are provided in one way slab in one side (At shorter span), but in two way slab we provided bars in both ways.

4. In Flat plate slabs the main bars are provided in one direction at bottom of the distribution bar (in shorter span).

5. Main bars in the slabs won’t be less than 8 mm if you are using (H.Y.S.D) or 10 mm if you are using (Plain bars).

DISTRIBUTION BARS IN SLAB:

1. Distribution reinforcement bar is to provide at the longer side span of the slab.

2. Distribution bar are design to distribute the super imposed load equally or counter the Shrinkage stresseswhich are developed due to Temperature variation (Winter,Summer).

3. In Flat plate slab the Distribution bars are provided in one direction at Top of main bar (in longer span).

4. The distribution bars aren’t be less than 8 mm in a diameter or not be more than 1/8 of the thickness of the R.C.C slabs.

5. The distribution bars are provided to hold the mesh in position and maintain the center to center c/c, bars spacing between main bars.

DIFFERENCE BETWEEN MAIN BARS AND DISTRIBUTION BARS:

1. The Main bars are normally provided at the bottom of distribution bar in slabs But Distribution bars are provided on the top of the main bar.

2. The Main bars are provided in the shorter span of the slabs But Distribution bars are provided in the longer spanof the slabs.

3. The main reinforcement was provided to counter the bending moment, tensile stresses and superimposed load But Distribution bars are used to distribute the load equally, resist the shrinkage stress (Temperature variation) or hold the mesh in his desire position.

4. Main  bars in the slab won’t be less than 8 mm if you are using (HYSD) or 10 mm if you are using (Plain bars)and theDistribution bars is also not less than 8 mm diameter and the bar won’t be more than 1/8 of the thickness of the slab
