# Calculation of Column BBS Manual /Automatic With Excel

**Calculation of Column Cutting length and Weight Calculation for Column Main Bar ( Column BBS )**

__Given Value From Drawing __

**Footing Depth – 300mm****Cover – Footing 50mm, Column -40mm****Beam Depth – 300 mm****UG Column – 1700 mm****Floor To Floor Height – 3000 mm****Parapet Wall – 500 mm**

__Now Calculate Cutting Length Of Column__

**Cutting Length = (Footing Depth-Cover – M Bar – D Bar) + L Length + UG + No of Beam**** + No of Floor + Parapet + Developed Length + Lapping Length – Band**

**M Bar = Footing Main bar, D Bar = Distribution Bar of Footing *

**Cutting Length = (300-50-12-12) + 300 + 1700 + (2 x 300) + (1 x 3000) + 500 + 50 – (2x2x12)**

**Cutting Length = (300-74) + 2000 + 600 + 3000 + 550 – 48**

**Cutting Length = 226 + 6150 – 48**

**Cutting Length = 6376- 48**

**Cutting Length of 1 Bar = 6328 mm = 6.33 m.**

**Now Calculate the weight of One Bar**

**One bar Length is 6.33 m**

**As we know formula for weight calculation of steel bar for 1 meter is = D ^{2}/162**

**Now we using 12 mm dia of bar for Column.**

**Then weight for 1-meter bar of 12 mm dia is**

**1 meter (12mm) = 12 ^{2}/162**

**1 meter (12mm) = 144/162**

**1 meter (12mm) = 0.888 KG/ m**

**Now our Cutting length of column for 1 Bar is 6.33 m**

**One bar weight = 6.33 *0.888 = 5.62Kg**

**Now as we in our column design 6 Nos of Bar in a single column**

**as we Calculated 1 Bar weight is 5.62 kg**

**Than 6 Nos of Bar is 5.62 x 6 = 33.82 kg per column**

Thank you tutorials tips civil for giving me this easy tips how to calculate Such a things thanks

sir is BBS mein aapne joggle length be consider kia hai kya ?

No, But Aap 1D le sakte hai

what does it mean for 2*2*12??

There are two 90 degree bends. For 90, we take 2d and multiply by the total bends. 2*2d

thanks sir

Thanks sir

Thanks sir

thanks to you for your comment.
