Can I notch the tension side of a beam?
It is recommended never to notch the tension side of the beam. Notching a beam on the tension side will reduce the strength of an LVL beam, according to Murphy Plywood. Notches cut perpendicular to grain can cause splitting along the length of the beam.
When should notching of glulam beams be avoided?
Notching of glulam members subject to transverse bending should be avoided whenever possible, especially on the tension side. Tension-side notching of glulam beams is not permitted except at end bearings, and then only under specific conditions.
Can a square hole be cut into an LVL beam?
In any construction project, especially new additions to homes or commercial buildings, there is a limited amount of space to run utilities such as electrical wires or water pipes. Sometimes the only available option is to port these utilities through the beam. As with all timber construction, a square hole should never be cut into an LVL beam.
Are LVL beams a good choice for my home?
LVL beams are a high-quality building product that is an excellent choice for most modern homes. LVL is especially a great choice to build homes and buildings with open floor plans due to the more extended manufacturing capabilities.
How much can you notch an LVL beam?
1/10Where LVL beams are notched at the ends for bearing over a support, the notch depth is recommended to not exceed 1/10 of the beam depth (Figure 1(e)).
Can you cut holes in LVL beam?
As with all timber construction, a square hole should never be cut into an LVL beam. Square cuts develop stress concentrations and are prone to splitting. Round (drilled) holes are preferred because they allow stresses to develop “more smoothly” around the opening.
Does notching a beam cause structural damage?
Over-notching or improperly bored hole of a wood post or beam can cause stress on the framing and create a crack or structural damage to the structural member.
Can a LVL be cut down?
Occasionally, it is necessary to rip down Murphy Company LVL (laminated veneer lumber) to a shallower depth that is not one of our standard manufactured depths. A “ripped” cut is one that occurs along the length of the beam parallel to the grain. There is no structural penalty for ripping down Murphy Company LVL.

Can you drill through engineered beams?
In engineered I-joists, you can drill holes up to 1-1/2 inch diameter almost anywhere in the web area between the flanges, provided they are at least 6 inches from the end of the I-Joist or load-bearing wall. You can drill holes up to 4 inches in diameter in the middle of the I-joist.
Does notching a beam weaken it?
Using a notched post and beam connection will lock the beam in place, secure it from rotating and resist wind uplift. Notching a post does not weaken the structural integrity of the wood support post because the load for the deck is transferred down through the post to the footings.
Can LVL be used vertically?
Different types of LVL can be used either horizontally or vertically. This use is not interchangeable. LVL is specified for its type of use such as for beams (horizontal) or columns (vertical). LVL has excellent size-to-strength and weight-to-strength ratios.
Is it OK to notch a joist?
One rule of thumb is to provide twice the distance between holes as the diameter of the largest hole. Also, notching the top of a joist weakens it less than notching the bottom, and you should avoid locating holes (and notches) near loose knots.
How much stronger is LVL than lumber?
two times strongerLaminated veneer lumber (LVL) studs can be two times stronger in compression and tension than standard framing lumber of the same dimension.
How far can a 12 inch LVL span?
As per general thumb rule and guidelines, a double 12″ lvl beam can allow span upto 20 feet far distance used for residential building or projects.
What size LVL Do I need to span 16 feet?
What size LVL header size for 16 foot span:- as per general thumb rule and guidelines for a 16 foot span, size of LVL header or GLULAM should be 14 to 16 inches deep and 3.5 inches wide, thus you need something like 2- 1.75″× 16″ (2- 1 3/4″× 16″) GLULAM or LVL header to span upto 16 feet.
Can LVL be used vertically?
Different types of LVL can be used either horizontally or vertically. This use is not interchangeable. LVL is specified for its type of use such as for beams (horizontal) or columns (vertical). LVL has excellent size-to-strength and weight-to-strength ratios.
What is an LVL beam?
Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. It is typically used for headers, beams, rimboard, and edge-forming material.
How do you secure level?

It.
How to get to finished LVL beam?
The process to get to a finished LVL beam starts with debarking the log, then rotary peeling the veneer to send the sheets to the jet tube dryers to reduce the moisture content to 8-10%.
How long is a LVL beam?
Generally, you can find LVL beams in 4-foot increments starting at 24 feet and going up to 44 feet long, with special orders up to 60 feet. LVL beam thickness is usually between 1 ¾ and 7 inches.
What is LVL in wood?
LVL stands for Laminated Veneer Lumber and is similar to plywood in appearance. The difference is that plywood changes the grain’s direction with each layer, and LVL keeps the grain direction the same. LVL is typically made in a factory, straighter, more uniform, and stronger than traditional milled lumber. An LVL engineering process uses multiple layers of thin wood assembled with adhesives.
Can you drill holes in LVL beams?
You can, however, drill holes in the beam at predetermined zones where horizontal holes are permitted for passage of wires and conduit. You should not have vertical holes unless the beam width is 3 1/2 inches or more. Always consult with an engineer or architect before cutting or drilling any holes in an LVL beam.
Is LVL lumber waterproof?
A drawback in LVL is it is more susceptible to water damage and rot if it gets wet than traditional lumber. The adhesive on many LVL beams is waterproof, but that glue will start to delaminate with repeated water infiltration, weakening the LVL beam. LVL work for interior and dry location applications.
Is LVL wood even strength?
Uneven Strength – Another downside is that LVL is very strong, but only on one axis, because of the stacking of layers with the grain running in the same direction. You should never stack other materials on top of LVL wood and only load it in one direction.
Is LVL wood susceptible to defects?
LVL wood is susceptible to defects. Here are some of them:
How much depth can you notch without an engineer?
If I am reading it right, a quick google, shows that you can notch an LVL 10% of the depth without being an engineer. Anymore than that and you need to break out the engineers, but it can be done:
Why did Superior double the beam pocket?
(Or it could just be a coincidence that they chose to place the smallest portion of the wall in that location). Regardless, it would have been much easier to have Superior put the appropriate beam pocket in that location, than to calculate the notch for the beam.
Is shear the only issue with bending load?
Have your engineer run the calcs and you'll see why. As far as the bending load, at midspan (max) it makes pretty much no difference. Shear is the only issue.
Where is the maximum bending moment?
Almost every beam is sized based on the minimum depth necessary to provide adequate bending strength at the maximum bending moment, which occurs in the middle of the span of most beams (there is zero bending moment at the ends).
Does a notch make beam X less in depth?
I disagree Kevin. The notch has now made that beam X less in depth at the end of it where it is bearing. we see that stupid old-school idea all the time up here where floor joists are notched to a ledger. We pad the ledger and then put a hanger under each joist so the entire depth of the joist is being used, not just the little "tab" at the end of it.
How much load can a beam hold?
If the beam is cut down 2 3/4" to 11 1/4", the max. live load capacity is reduced to about 200 lbs./lin. ft.
How much deflection is required for a 12 ft span?
Most large span beams (over 12 ft) are sized not for strength but to limit the deflection to L/360 which would be about 5/8 inch for an 18 ft span. That's "accepted engineering practice" and required by every national building code in the US since they started writing them. If your beam supports an attic and a roof it would have twice the required strength in bending but would deflect at max. loading, 2 or 3 times what is allowed by law.
How many LVLs are in an 8 foot door?
It appears that there are 2 different sets of LVLs in the 8 foot door? 2 9 1/4 for the door header, and one 14 inch that appears to stack on top of the plate.
What is the decisive answer to Don't accept the carpenter's (sic) line of "?
Don't accept the carpenter's (sic) line of "we do this all the time. No problem!" as the decisive answer.
Does He owe you written evidence that the beam is adequate?
He certainly owes you written evidence that the beam is adequate since the contract documents show something considerably stronger.
Can a builder design a LVL beam?
If a builder is allowed to design an LVL beam in your state and you agreed to let him do it, you will probably not be able to get a straight answer regarding this matter. I guess you could ask to see the design calculations he or some lumberyard did or the loading per lin ft and the manufacturer's chart he used.
What is laminated veneer lumber?
Laminated Veneer Lumber (LVL) is a manufactured structural wood product that is utilized when the strength requirements of a timber beam exceed that of your typical sawn lumber beam. LVLs are produced by taking wafer thin slices of wood and sandwiching them together (see photo below).
Can you cut a square hole into a LVL beam?
As with all timber construction, a square hole should never be cut into an LVL beam. Square cuts develop stress concentrations and are prone to splitting. Round (drilled) holes are preferred because they allow stresses to develop “more smoothly” around the opening.
