I am trying to find 4x beam size to get L/480 or less deflection with Structural Select Doug Fir and 10 + 60 PSF loading.
Span 124" supporting 86" of joist --> 5200LB total uniform load Span 56" supporting 89" of joist --> 2500LB Span 108" supporting 42" of joist --> 2250LB
"Sagulator" computations gives me 4x12 for the first and 4x8 for the other two. Anyone with data tables or better software: does this look right to you?
Are there other *free* online tools for this? (I used the AWC calculator for joists)
Cheers, Shawn
