BEAM SPAN TABLE LVL HOW TO

I scroll down to the Allowable Uniform Floor Loads because it uses at least L/360 in this case since it is drywall that would be sagging here. In this case, the Georgia Pacific GP Lam LVL tech sheet has 1, 2, 3, and 4 plys already built in. I then divide this by 2 and 3 to find my individual PLF capacity needed for 2 and 3 ply of LVL EDIT:If using a chart for single 1-3/4' only. I'd say that is more than 10PSF but online searches seem to treat person in attic as 10PSF?įor the first part of this, I am taking 20PSF x 14' (half the 28') to get my PLF of 280.

5PSF for attic dead load of insulation and 2圆 framing (stick framed with rafters, ridge board, etc and not webbed truss), 5PSF for two layers of drywall/mud, and 10PSF for what would be live load of someone crawling around in attic.

I was going to use 20PSF for this rating. The ceiling joists have 5/8' drywall - let's say 2 layers - and then attic space above with blow in insulation. The ceiling joists are for two rooms, each room for this example has a length of 14' so the 'Span Carried' would be 28' but technically when I run the PSF I would halve this I assume? A LVL beam to be installed to support ceiling joists that are *not* continuous, as in they tie into the LVL beam. I believe this is the PLF rating? It seems a little too straightforward using the tech sheet so I want to make sure I am calculating correctly.

BEAM SPAN TABLE LVL HOW TO

I'm wanting to learn how to properly size an LVL beam when the specifics do not simply fall under the manufacture's generic span chart giving two options for premade spans.
