2 pine is the the most common so the field is pre-selected at that. For example if a room is 10′ inside to inside and the joists are cut 10′ 7″ so they will bear fully on both walls, then the span will be 10′. This will be slightly less than the length of the board. Most lay outs are on 16″ so the field is pre-selected.

Select the on center spacing for the joists.

The highest is a fully loaded floor (70 pounds per square foot). The lowest is a plain ceiling joist with no storage (10 pounds per square foot). We have engineered this calculator to provide spans which will produce a solid built house with no bounce in the floors or any swags in the ceiling.

The resulting spans are less than the 2012 IRC codes but they are to our standards at Scott’s Framing. The spans for joists according to the code is far more than we find acceptable.

If you can draw a quick house plan, that'd be best.Calculate the span for floor and ceiling joist with this free and simple online calculator. At that point, you'll want to consider the condition of your slab because a 20' 18' LVL will impart some heavy point loads even with a 7+' bearing. 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. The American Wood Council (AWC) Span Calculator for Wood Joists and Rafters (Span Calc) performs calculations for all species and grades of commercially. It was a bit more complex than I expected.

There were a lot of other little things I learned while working with my friend. If the jack studs land on plywood, you could push right through it and have your beam fall down. You may have to add sister joists under the floor. One BIG thing that I never saw mentioned on the internet and I have never seen on any home show that does this is- MAKE SURE You support the jack studs UNDER the floor. I could have gone to a 12' if we used 3 beams, but that would make the wall 6' wide. In my example, I have a single floor (only attic above the beam), and a 9' span for the opening. It really depends on a lot of factors including how many floors are above the space, what area of the country (snow load), size of the opening and other things. I did not find a good calculator that I felt I could trust. I just put up a beam with the help of a contractor friend.
