snow load from roof) then you're very likely looking at a 4-PLY 18" LVL which of course needs to be bolted (2 rows) and glued. If there's a lot of floor on it and you're in a higher-than-normal LL area (i.e. For a 10' span, a 2-Ply 14" LVL is likely to work with a post for normal LL/DL (no hurricane / high wind areas or heavy snow loading).įor a 20' clear span, I would bid a 3-PLY 18" LVL. If you have heavy point loads from the roof joists / beams coming down then you're going to be dealing with some odd beam loads (uplift in some bearing points). That's assuming uniform loading from the wall(s) above. Without being able to accurately determine the loads I'm going to go ahead and say a 2-Ply 14" LVL will fail L/360 deflection by a fair margin.Ī mid-span post will make considerably less beam work so long as the clear spans are very similar. That being said, this is my personal opinion to give you direction. I engineered wood frame buildings for 4 years including beam sizing, etc. Try DIY on the Fediverse or Filter by Flair Please post such content to the appropriate subreddits.Ĭome join us on Discord for real time help and discussion.
