A_Moore Posted April 28, 2022 Share Posted April 28, 2022 Working on a plan... When I ran the build, framing, floor command, the I-joists were bound by doubled 2x12's below the 2nd floor walls. That's understandable, but I don't know if the two doubled 2x12's can support the 2nd floor/joists at the 24'-4-1/2" clear span (highlighted in attachment). This may be more of a structural question. Any advice or input would be greatly appreciated. Thanks, Andrew Link to comment Share on other sites More sharing options...
Rookie65 Posted April 28, 2022 Share Posted April 28, 2022 The program knows nothing about structural requirements. That is for an engineer to calculate, or you to consult the span charts for your region from the building code. Link to comment Share on other sites More sharing options...

A_Moore Posted April 28, 2022 Author Share Posted April 28, 2022 After more research, I found ForteWEB which is a handy tool for I-Joists spans, beams etc. Link to comment Share on other sites More sharing options...
Rookie65 Posted April 28, 2022 Share Posted April 28, 2022 That's fine, yet most municipalities will require any engineered material to have calculations passed in with the permit application before they'll approve a design. So unless you're an engineer, notate those items to be verified by others. A lot of lumberyards can get the calculations from their engineered material suppliers to submit.
