My walls are constructed using ICF. The walls are 8" think reinforced concrete with a top plate and a and a 3" by 19" GL beam (column), bolted to the concrete. The wall is Nudura 8" reinforced concrete, 5000 psi. #5 60 ksi rebar 8" oc vertical and 12" oc horizontal.
This not your regular...
I have two GL beams side by side (5" by 19") total beam width is 10 inches.
From truss calculations provided by the structural engineer, the Top Cord Live Load is 30 psf, TC snow load is 30 psf and TC dead load is 10 psf. I added the bottom cord load of 10 psf as well for a total of 80 psf.
I...
i appreciate your comments. The beam were collected from a salvage. They in the the original wrap and were give to me. We are building with ICF and the only reason we used two was because 1) they were free 2) we didn't have any other use for them and 3) the combined 10" thickness worked well...
I would like to take you up on your offer and would like a copy of the APA paper. I was wondering how you send a PDF? I posted my contact info and that was shut down pretty quick. Do you have any idea how I would get calcs to you?
Thanks Don,
I appreciate the feed back. I will be running numbers when I get back to Denver.......snow pending. I will report back to the group what a find......
Thanks for the info. I had to jump a plane and I will be south for a day or so. I will run the numbers once I get back and can run down my truss calcs.
I appreciate the input and feedback.

The beams in and the roof is on. So it's either it's cut it or don't. I hear what you are saying.
Do you know any one in town that sells GL beams and can provide technical support? I am now curious how they are manufactured and how they create the stronger tensile members at the beam...
I did the geotech investigation and the foundation design and used a structural for the ICF and beefed it up from there. The beams, well you would have to see the beams, in it's present configuration it is obviously hell for stout.
Now that I am considering cutting into the beam, I have a...
The GLs were free so the price was just about perfect. Otherwise, the beam would have been steel. I am an engineer, but the Geotech type. Structural design using timber and specifically GL is well outside my comfort zone.
Do you know anyone in the Denver area, that by chance, would have GL...
I am think through options here and could I not 1) bolt the beams together there by increasing the section modulus 2)place a steel plate at the cut base to increase/replace lost tensile capacity and there by increasing the section modulus?
Hey guys thanks for the input. The beams are already installed and the roof in. The builder set the garage door opening at 7'6" and I would like to take it up to 8'. So cutting would be the only option.
The beams appears to be well over sized. I have two 5" by 19 beams, side by side...
I hear what you are saying, but it seams counter intuitive. I would expect that the beam performance would be comparable to an equivalent lesser beam thickness with some reduction. Do you have a basis or technical paper that addresses cutting abeam?
Thanks
