What is beam depth vs width?
Width is the horizontal face dimension; depth is the vertical dimension of the cross-section.
Beam Concrete Calculator
Calculate concrete volume for rectangular beams by span, cross-section, and quantity.
Beam Concrete Calculator Formula
- Beam Cross-Section
Width × Depth - Single Beam Volume
Cross-section × Span Length - Total Volume
Single beam volume × Quantity - Wastage Allowance
Total volume × (1 + Wastage ÷ 100)
Assumptions
- Beams are modelled as rectangular prisms with uniform cross-section along the span.
- Haunches, drop panels, and stirrup cages are excluded from volume.
- Span length is the clear horizontal length of each beam.
Frequently Asked Questions
Can I use this for lintels?
Yes. Short horizontal members over openings can be modelled as beams with appropriate span and section.
How do I calculate multiple identical beams?
Enter one beam’s dimensions and set quantity to the total number of beams.
