How to Use This Calculator
- Enter the clear span in ft between supports and the total superimposed load in psf (live + SDL).
- Set the double-tee flange width in ft (common sizes: 8, 10, or 12 ft).
- Enter composite topping thickness in inches (0 for untopped, 2–4 in for composite systems).
- Read Recommended DT Depth (in) — the shallowest standard section that satisfies both span and load.
- Verify that Governing Utilization (%) is below 100% — above 100% requires a deeper or higher-strength section.
- Note Total Piece Weight (lbs) and Estimated Camber (in) for crane planning and floor levelness requirements.
