Practical tools for measured work
Deck load demand worksheet
Calculate uniform deck load demand and whole support-line reactions for one simple span, using entered loads.
How it works
Multiply loaded area by the entered surface loads. For one uniformly loaded simple span, equilibrium gives half the total load to each support line. DCA6 uses 40 psf live and 10 psf dead load within its own limited scope; these are not universal jurisdiction requirements.
Before using the result
- Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
- Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
- When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.
Limitations
Demand only, not deck capacity. No post-by-post distribution, cantilever, point load, hot tub, lateral load, uplift or connection design. Confirm actual geometry, material, section and governing loads with a qualified designer; support reactions here are entire lines, not individual posts.
Frequently asked questions
What should I verify before using this result?
Recheck the physical measurements, confirm that every input uses the displayed unit, and compare the result with the applicable drawing, product specification, code requirement or test piece.
Why might the finished result differ?
Real work can include thickness, kerf, seams, tolerances, hardware allowances, installation clearances or site conditions that are outside the calculation. The limitations section identifies the main exclusions for this tool.
