Bar Bending Schedule for Slab, Estimation of Steel Reinforcement in Slab
Bar Bending schedule has a key function to play in determining the totals of reinforcement within structure. So as to determine the Bar bending schedule with regard to slab or steel reinforcement within Slab, It is suggested to gain knowledge of the fundamentals of Bar Bending schedule as well as in what way to take up concrete cover with regard to various parts of a structure.
There are sixteen distinct sorts of slabs in construction. Also, the slab’s thickness usually differs amid 4″ to 8″. Moreover, 6″ [0.15 m] slab thickness is usually adopted. With regard to infrequently weighty loads 8″ and over width/thickness slabs are adopted.
In that piece of writing, in order to find out the Steel reinforcement’s Estimation needed with regard to a Slab to operate on that an arrangement is contemplated as described underneath. Generally, slabs are categorized into 2 sorts; one way Slab as well as two way slab, to understand additionally regarding the contrasts, kindly check out the following.
In one way Slab, major/main bars are offered in a short direction [Cranked bars] as well as distribution bars are offered in long direction [Straight bars]. While in two way slab, major/main bars [cranked bars] are offered in the two directions. Generally, the two way slab is accepted at the time the width as well as length of the slab are in excess of 4 m.
Also, in order to make one just right in Bar Bending Schedule with regard to a slab, one way Slab and two way slab are considered as exhibited in the representation. Furthermore, distribution bars as well as main bars are offered in the one way Slab. Moreover, in two way slab, distribution bars are offered on the two sides of the slab.
Furthermore, Distribution bars - Those bars are straight bars.
Also, main bars - Those bars are cranked bars. Furthermore, main bars are bent at an angle of forty five Degree having the length of 0.42D
Wherein, D = Slab’s Depth - Bottom cover – Top cover
Extra Bars - The extra bar is offered on the base of Cranked bars to uphold the structure/framework of the slab. Moreover, the Extra bar’s length is L/4.
Measures to compute the Reinforcement needed for Slab
- Subtract the cover with regard to determining the bar’s length.
- Calculate the distribution bar’s length
- Compute the quantity of “D” [Slab’s Depth - Bottom cover - Top cover]
- Determine the number of Bars
- Calculate the overall wt of steel needed with regard to slab reinforcement.
