How to calculate the self-weight of a column
Given data:
- Column size = 300mm x 300mm
- Column Height = 3.1m
- Concrete Density = 2400kg/m³
- Steel Density = 7850kg/m³
Column self-weight = L x B x H
Column self-weight =300mm x 300mm x 3.1m
Change into meter
Column self-weight = 0.3 x 0.3 x 3.1 ⇒ 0.279 m³
Then 0.279 X 2400 *Dersity concrete =2400 kg/m³
⇒ 669.6 kg
1% Steel used in column
1/100 x 0.279 x 7850 *Density Steel = 7850 kg/m³
⇒ 21.90 kg
Total self-weight of column = 669.6 + 21.90 ⇒ 692kg
This video will show how to find the RCC slab, beam, and column self-weight. The formula calculates the self-weight of any RCC structure:
Self-weight or dead load = density (γ) × volume
