Structural Load Calculator
Calculate dead loads, live loads, and total structural loads
Load Parameters
Weight of structure (10-20 PSF typical)
Occupancy load (40 PSF residential, 50 PSF commercial)
For roofs only (varies by location)
Typical Values
Residential Floor: 40 PSF live
Commercial Floor: 50-100 PSF live
Storage: 125+ PSF live
Roof: 20 PSF live + snow
Load Analysis
Total Dead Load
2000 lbs
10 PSF
Total Live Load
8000 lbs
40 PSF
Total Combined Load
10000 lbs
Governing Load (per code)
10000 lbs
50.0 PSF
Point Load per Support
2500 lbs
Assuming 4 support points
Note: Load combinations per IBC:
• D + L (Dead + Live)
• D + S (Dead + Snow)
• D + 0.75L + 0.75S
