Practical tools for measured work
DCA6 Southern Pine span reference
Look up the limited Southern Pine No. 2 span subset from AWC DCA6-2015 Tables 2 and 3A with explicit scope checks.
How it works
Exact Southern Pine rows from AWC DCA6-2015 Tables 2 and 3A. Beam input uses the next published joist-span column at or above your input, never interpolation. Joist spacing must match a published column. The source assumes No. 2 grade, wet service and 40 + 10 psf loads.
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
Reference lookup is not a complete design approval. Confirm the full DCA6 applicability, ledger, hangers, bearing, built-up beam fastening, posts, lateral restraint, guard connections and local adoption. This subset does not size overhangs, incised lumber, other species, other loads or multi-span beams. Changing member type may require choosing a valid assembly again.
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.
