**Calculate The Bar Bending Schedule For Plinth Beam**

In this topic, I will discuss how to calculate the bar bending schedule for the plinth beam |Calculate The Bar Bending Schedule For Plinth Beam |what is the plinth beam.

**What is the Plinth Beam.?**

A plinth beam is a beam that is constructed between the foundation and wall. the main purpose of providing the plinth beam is to prevent the extend the crack between the foundation and the wall.

**Calculate The Bar Bending Schedule For Plinth Beam**

**Given data **

Beam clear span=2500mm=2.5m

Length of beam =300mm=0.300m

Width of beam =380mm=0.380m

Number of main bar=4 No’s

Diameter of main bar =16mm

Diameter of stirrups=8mm

Spacing of stirrups=150mm

Concrete cover=25mm

**Solution **

**Main bar diameter=16mm**

Cutting length of main bar= clearspan+2 x Ld- 2bends 90 degree

Ld=40d

2bends 90degree= 2bends bothe side and 90dgree bends =2d

Cutting length of main bar=2500+(2x40d)-2x2d

Cutting length of main bar=2500+(2x40x16)-(2x2x16)

**Cutting length of main bar=2500+1280-64=3716mm=3.716m**

Number of bar= 4No’s

The total length of the main bar = length of one bar x number of bar

**Total length of main bar =3.716 x 4=14.864m**

**Weight of the main bar**

Weight of main bar=d²/162.25x total length

**Weight of main bar=(16)²/162.25x 14.864=23.45kg=24kg**

**Stirrups**

Cutting length of stirrups= 2 x (length +width)+2x hook length -3x 90 degree bends -2 x 135degree bends

90 degree bends=2d

135 degree bends =3d

Hook length =10d

Cutting length of stirrups=2x(250+330)+2x10x8-(3x2x8)-(2x3x8)

**Cutting length of stirrups=1160+160-48-48=1244mm=1.224m**

**Number of Stirrups**

Number of Stirrups=clear span of beam /spacing +1

**Number of Stirrups=2500/150+1=17.67=18No’s**

The total length of stirrups=Length of one stirrup x number of stirrups

**Total length of stirrups=1.224 x 18=22.032m**

**Weight of Stirrups**

Weight of Stirrups=d2/162.25 x total length

**Weight of Stirrups=(8)2/162.25 x 22.032=8.69=9kg**
