# Reinforcement Details In Beams And Slabs

|## Beam Reinforcement Details:

Beams are essentially provided with main reinforcement on the tension side for flexure and transverse reinforcement for shear and torsion.

## Tension Reinforcement:

The minimum tension reinforcement is denoted by the given formula

As = (0.85bd/fy)

Where, As = Minimum quantity of tension reinforcement

b = breadth of the beam,

d = effective depth,

fy = strength of reinforcement in N/mm2

D = Overall depth of the member.

The minimum tension reinforcement (As) should not be less than the value of (0.85bd/fy).

And the maximum quantity of tension reinforcement should not be greater than the value of 0.04bd.

## Compression Reinforcement:

Stirrups should be provided with the compression reinforcement in beams for lateral restraint.

The maximum quantity of compression reinforcement should not cross 0.04bd.

## Side Face Reinforcement:

At the point when the depth of web or rib in a beam crosses 750 mm, the side face reinforcement of cross sectional area at the very least 0.01% of the web zone is to be given and disseminated similarly on two appearances and the dividing of the bars not cross 300 mm thickness whichever is smaller.

## Transverse Or Shear Reinforcement:

The minimum quantity of shear reinforcement is computed by the given formula

Asv ≥ (0.4bSv/0.87fy)

Where Asv = Total cross-sectional area of stirrups legs in shear.

Sv = Spacing of stirrups along the length of the member.

b = The breadth of the beam or the web in a flanged member.

fy = Characteristic strength of stirrups reinforcement, which should not cross 415 N/mm2.

For vertical stirrups, the maximum spacing of shear reinforcement should not cross 0.75d.

and for inclined stirrups d is considered as 450.

The maximum limit of spacing is 300 mm.

## Slab Reinforcement Details:
