![]() ![]() We don't mind having a weirdly wide beam that intrudes into the room if the LVL needs to be tripled (or more?). The beam can't be more than 6" high or we cut too much into the headroom. Stagger the bolts and make sure the bolts are placed a minimum of 2 1/2 inches from the edge of the beam. ![]() An example of a regular bolting pattern might be 1/2 inch diameter or 5/8 inch diameter bolts spaced 16 inches on center. There are a bunch of other calculations and abbreviations on his sheet that I don't understand but can post if needed. The first method is an empirical method, which is purely based on what has worked well in the past. The calculation is that the Live Load is 808 and Dead Load is 257 for a Total Load of 1065#/lf. ![]() I wonder if anyone here knows their LVL strengths or can point me to tables online. I don't want to ask my neighbor for more assistance, he's already been so generous, and engineering firms here are overwhelmed and taking a long time to get back to us (none have yet). They are typically used to reduce the structural depth of an equivalent wood-only beam. No matter where they’re used, they install quickly with little or no waste. They can easily be built-up on site to reduce heavy lifting. Then I had a couple of contractors bid the project who both said that very likely a manufactured wood beam would be just as strong and much easier to work with. A Flitch Beam is a composite section comprised of one or more steel plates attached to a wood beam. Microllam® LVL beams work well in applications all over the house. He calculated a flitch beam of 1/2" x 6" steel between 2 x 6"s. My wonderful neighbor who is a retired structural engineer designed a beam I can use to add 8' sliding glass doors to our lower level family room.
