Why we use LVL for beams and headers
Тәжірибелік нұсқаулар және стиль
LVL- Laminated Veneer Lumber is an engineered wood product made up of multiple layers of wood glued together.
Because it’s manmade it’s stronger and more consistent than conventional lumber.
It’s used for such things as headers and beams.
A bunch of people commented on my header video asking about this exact shot- thinking it two separate beams, but you can see this is just a splice in the outer veneer.
Here you can see a splice on the opposite side.
Since you can special order these beams up to 60’ the veneers have splices, but they are always staggered.
To show just how strong this LVL is - I set up a ramp to see if it could support half the weight of my skid steer.
Keep in mind it’s much stronger when it’s vertical than when lying flat like this.
After the first run I reconfigured the ramp so the weight of the skid steer would be more forward.
The skid steer weighs around 9000 lbs, so the 2 plies of LVL are holding roughly 4500 lbs.
I considered trying it with one ply but wasn’t sure how that would work out. @hausplans

Good video! In my current home built in 2003 they used 4 such beams, two were in the garage as header beams and they were 3 1/2 x12” and two were holding up the staircase going to the basement, these were subs for 2x10’s and were 16’ long and 10” wide, they spanned from an I beam to the foundation wall. I did have a laminated beam in my garage (previous home) that was 20’ long across the whole front of the garage above the 16’ garage door. All of these are still working fine with no problems. Thanks.

@@Dogfrost5 Right, but it matters in terms of how much time you have to escape or rescue people. The test they did was by placing a load on the beam and measuring how much time it could support the weight while on fire before collapsing. I forget what the specific number he claimed was, but it was significant. Like 1:4 or something. Either way you have to replace the structure, but it could potentially mean the difference between losing family members or not. This guy (my coworker) talks a big game too, and I'm repeating what he said to me. It could be bullshit, so don't take it as gospel...I don't doubt that he saw the test, but I might question his interpretation of the results.

It's not just the stacking, it's the epoxy between the layers. Stuff is extremely strong. It has all that surface area for adhesion on all the layers, strong isn't even the word for it in all honesty. I would like to see tests being done to see how strong it really is.
I questioned that engineered lumber today when I was looking at a massive house being built down the street from me. I guess I was wrong. I just thought they can't acquire solid beams of the size anymore because it is too expensive. You should see the beams of my next-door neighbors house. Built in 1870. Beams are thick as hell. They just dont have trees thick enough anymore. House is solid as a rock. Boulder foundation as well

Yes, it's not just about being able to manufacture a beam of whatever size is required. The weakest parts of a board or beam and where they are much more likely to fail under stress is usually where there are knots and other grain imperfections. LVLs address this not because the constituent vaneers don't have those imperfections, but because the imperfections are made smaller and distributed evenly throughout the beam, and there are no weak points like you see with conventional lumber.

I've been a carpenter for 50 years. Lam beams and LVL started being used extensively about 25-30 years ago. Up until then pretty much everything we built with was dimensional Lumber. Remember that Lam beams and ldls are all glued together. There is not a glue that has ever been developed that doesn't dry out. When it dries out it loses its strength. It's inevitable. During my last ten years I've had at least a dozen jobs propping up and trying to stiffen up these glue beams that had already started to give. I've also worked on 250 year old houses that were still structurally sound. It's planned obsolescence in the homebuilding industry.

Not really a great example of the strength due to fact that the weight of that machine is spread out across the length of that track
The track loader test didn’t prove anything because the weight on a attack is evenly distributed, so effectively you weren’t putting as much weight in the LVL compared to if you had used a wheeled skid steer. A better test with the track loader would have been to put your bucket down at the mid point and then push down to lift the entire machine up and point load the beam. That would truly illustrate the beam’s strength.

Fun fact, that lvl isn't holding up your skid steer. The tracks of the skid steer are holding up the skid steer. That's why it's got tracks, because the load is distributed along the length. Drive your skid steer across a 2ft ditch and low and behold it won't snap in half.
