Making a Glulam Beam. Thread Tools. I am rebuilding a patio cover that had too small of a beam 4x6 that was used and it is beginning to crack and bend. I calculated the loads and for the 16 ft.

Has anyone tried to make their own beam, like a pre-manufactured Glulam Beam? Watching some of the do-it-yourself shows, it did not look difficult. Any tips? View Public Profile. Find all posts by ellersk.Glued laminated timber, also known as glulam, is a versatile and innovative construction material that builders love to use for commercial and residential projects.

Not only is it a solid material, but it is widely available on the market. Although you can attempt to make do-it-yourself laminated beams or buy used glulam beams for sale, it is highly recommended that you purchase them from a reliable source. If you make just one small mistake when trying to make your own glulam, you can severely damage your entire project.

Glue-laminated timber has increasingly become popular in residential homes since Builders and homeowners like glulam beams because you can purchase them from building material dealers and distributors in various stock sizes.

Glulam, like most engineered wood products, is very easy to work with, and you don't have to worry about the look of the wood changing over time.

How to Replace a Load-Bearing Wall With a Support Beam

Glulam is an engineered product that is created by bonding individual pieces of lumber together. Typically, glulam has a thickness of 2 inches or less. When individual pieces of lumber are end-joined together, they create longer lengths. These long lengths are known as laminations. Laminations are face-bonded together, and that creates the finished product.

Glulam is considered to be one of the most versatile engineered wood products because it can be shaped into different forms. Also, on a pound for pound basis, it can be on the same level of strength as steel. When shaped, one can create straight beams or curved members. You can often find glulam used for garage door headers, floor trusses, ridge beams and purlins, cantilever beam systems and columns.

Glulams is strong and dimensionally stable, so you can use it for a variety of applications. Some even use glulam for long-span roof beams and heavily loaded floor beams. One can find stock beams that come in foot lengths, and they are used for spans upward of 20, 24 and even 28 feet or higher. Many builders like to use stock glulam for framing large window openings and creating rooms without columns supports because these supports will inevitably interrupt the flow of the room.

Although you can make DIY structural wood beams or glulam timbers yourself, they are highly engineered components. Glulam is manufactured from specially selected and positioned lumber laminations, and if you cut a notch or drill a hole in the wrong place, it can seriously affect the load-carrying capacity.

Do it Yourself Laminated Beams

It is recommended to purchase glulam that has already been manufactured because you won't have an issue when trying to build. If you're worried about finding glulam beams, they are readily available in stock or custom sizes. Stock glulam is available in all major market areas. You can find stock glulam that is available in commonly used dimensions and cut to length when the beam is ordered.

It is also relatively easy to find stick glulam beams available in I-joist-compatible depths. If you're using glulam for nonresidential applications, you can also have custom members made. Glulam is available in a variety of appearance classifications, but the appearance grades aren't related to the structural characteristics. For example, "framing" beams are used in concealed applications, whereas "architectural" beams are used for applications where the beams are exposed to view.

Not only is glulam super versatile, but it is also made out of eco-friendly material that has low formaldehyde levels as well. Hunker may earn compensation through affiliate links in this story.

Like all engineered wood products, glulam beams are resource-efficient with highly predictable structural performance. As headers, floor beams and columns, the materials are easy to specify, even easier to work with, and the timeless aesthetics of wood remain unchallenged by other building materials.

Glulam is an engineered stress-rated product created by bonding together individual pieces of lumber having a nominal thickness of 2 inches or less. Individual pieces of lumber are end-joined together to create long lengths referred to as laminations.

These laminations are then face-bonded together to create the finished product. On a pound-for-pound basis, conventional glulam can achieve allowable strengths equivalent to steel. Glulam is also among the most versatile of the engineered wood products. It can be shaped into forms ranging from straight beams to complex curved members. Typical residential applications include garage door headers, floor girders, ridge beams and purlins, cantilever beam systems and columns.

APA EWS-trademarked Engineered Wood System glulam beams are supplied with either zero camber or a very flat factory built-in camber, which makes it easy to connect glulam with other wood frame components. Figures 1 through 5 illustrate some of the many simple connection details that can be used with glulam residential garage door headers.

Since glulam timbers are highly engineered components manufactured from specially selected and positioned lumber laminations, an improperly cut notch or a hole drilled in the wrong place can seriously affect the load carrying capacity of the member. Field notching, cutting or drilling of a glulam beam, particularly on the tension side of the member, should be avoided.

Field conditions may require making a cut, notch or hole that was not originally anticipated.

In some instances, these can be made in areas of the glulam, which are not highly stressed and will thus have minimal effect on the structural capacity of the member. One of the most challenging design areas in a home is the narrow wall adjacent to the garage door opening.

This short wall section must withstand the same lateral forces that bear on other, larger wall and roof sections of the home. The APA Sturd-I-Frame system gives builders and homeowners a design solution that allows for the narrow walls while providing the necessary strength and stiffness.

Glulam beams are readily available in the long lengths that are needed to extend the header over the adjacent walls. The vertical wall segment is wood structural-panel sheathing that overlaps the glulam header and is attached with nails in a specified grid pattern.

At the base of the wall, a hold-down connector attaches the wall segment to the foundation see Figure 6. These two moment-resisting connections, combined with the bending capacity of the vertical segment and glulam header, provide the lateral resistance normally facilitated by shear walls or braced wall sections of a substantially greater width.

Homeowners appreciate the natural beauty of wood and the warmth it brings to interior spaces.

They also enjoy the consistent, long-lasting performance of wood. Unlike large solid sawn or built-up timber beams, glulam, which is manufactured from kiln-dried lumber, will exhibit minimal shrinkage and warping, which ensures a level floor surface. In addition, floors have minimal nail popping and fewer squeaks. Framers find that glulam floor beams are easier to work with than comparable steel beams.

Nailers are not needed as they are with steel beams, and nail-on joist hangers can easily be accommodated. Glulam beams can span long distances using lighter-weight members with minimal need for intermediate supports, opening the design possibilities in a host of applications.

Everyone, from homeowner to homebuilder to home designer, can appreciate the expanded design flexibility of wood.

Thread starter Matthew S. Whiting Start date Jul 4, Matthew S. The trouble is, it is nearly impossible to build glulams of this size correctly without large equipment. Proper means both amount of clamping pressure and its uniformity. It is unlikely that this will be achieved using screws. I'm all for DIY work and do a lot myself, but some things are just better done in a factory setting. I do my own wiring, but I don't make my own wire.

I drive lots of nails, but I don't make my own nails. Glulams are in this category. They aren't all that expensive and the time required to build you own is very high and the likelihood of a good outcome is fairly low. And the consequences of a failure are very high. If this was purely a decorative piece, then that would be completely different, but it sounds like he's talking about building structural elements.

Re: Homemade Glulam beams??

This isn't a good place for experimentation. Ervin said:. Well folks, I've been encouraged and discouraged by the responses I've seen here. I appreciate them all. I learned a long time ago not to ask the questions if you don't want the answers.The theoretical size of a load bearing beam required to support a particular weight is easy to calculate, but the choice of the actual beam depends on taking into account the factors of the particular situation. To address possible imperfections and weak spots in the wooden beams, it is common to install the required cross section by placing several smaller beams side by side.

Beams on inch centers will also reinforce each other.

The theoretical calculation also usually assumes an even distribution of weight and that the ends of the beams are not only supported but held rigid. Make sure that this applies in the particular case or use oversized beams. Calculate the weight the beam must support. For a flat roof with snow loading, this is 25 lbs.

For rooms which are heavily frequented, it may be 50 lbs. Multiply the loading per square foot by the area in square feet of the surface which the beams will be supporting. Divide by the number of beams which will be installed to get the loading per beam. Calculate the maximum bending moment for the wooden beams. The bending moment is the length of the span times the weight to be supported divided by 8. For a beam spanning a foot room and supporting a weight of lbs. Calculate the beam's section modulus by dividing the maximum bending moment by the allowable fiber stress for wooden beams.

The latter is 1, pounds per square inch. Multiply the maximum bending moment of foot pounds by 12 to get 10, inch-pounds.

Divide 10, inch-pounds by 1, pounds per square inch to get the section modulus required of 9. Calculate the section modulus for the different beams which you could use. The formula for the section modulus is beam width times beam depth squared divided by 6. A two 2-by-6 standard beam has actual dimensions of 1.

A 2-by-8 beam would be sufficient. Two 2-by-4 beams together would not be enough. Standard 2-by beams on inch centers are used to span 15 feet. Step 1 Calculate the weight the beam must support. Step 2 Calculate the maximum bending moment for the wooden beams. Step 3 Calculate the beam's section modulus by dividing the maximum bending moment by the allowable fiber stress for wooden beams. Step 4 Calculate the section modulus for the different beams which you could use.I am building a ground level deck max 24" of the ground.

It is L shaped and will have 2 long beams The beams will be 3-ply PT SP 2 2x12's using 12' long lumber cut to fit the distances between the supporting posts. Should I make each beam a continuous beam or make should I make each long beam up out of separate beams the length of each distance between support posts "on center" that but in the middle of the support bracket? The beams will be top loaded. There will be no joist hangers on the sides. Given the environment, I want to use stainless steel fasteners and preferably screws structural screws.

Which one would you recommend. What pattern would you recommend for the fasteners? I am in NY state, perhaps the code dictates some of this but I have not been able to find any information in the code. Editor Comments Q1: I would recommend a single continuous beam made of staggered dimensional lumber that can span the required distance.

I will explain this further in the video below. Longer is even better. But if you are in an environment where salt air or spray is an issue I would use stainless steel screws.

If you can get screws that would be even better. And an RSS screw is the finest. Q2: b Use a zig-zag pattern and double up on screws at the ends of each board. One above the other separated by about ". Set them at 16 inches on center distances from each other and about " in from the edge of the board.

Check out this video for more information: Video Recap Have you ever had to build a beam, a big triple ply beam that's longer than the lumber that you can buy, let's say 30 feet or so? How do you do it? Well, we've got a question that came in today from Patrick from Long Island.

And I'm going to explain to you and to Patrick how best to do that. So, Patrick writes: "I'm building a ground level deck, maximum 24 inches above the ground, it's L-shaped and it'll have two long beams.

One is 27 and a half feet, the other one is 31 feet. The beams will be three-ply pressure-treated SP number two 2 by 12s, using foot long lumber cut to fit the distances between the supporting posts. Question one, should I make each beam a continuous beam, or should I make each beam long enough out of separate beams the length of each distance between the support post and on center with those support posts below the beam? It could be done the way you're proposing, but I just would never do that.

A lot of problems that could arise from that and it's very easy to build a continuous beam. So, what you're going to do here if you're working with foot lengths, I would ensure that one of those plies, one of those 2 by 12s is butt joined directly over the central support post. I'm presuming you have at least three given that length.Interior walls create privacy, define spaces, and sometimes bear the weight of the level above.

Walls have defined floorplans for centuries. Starting in the s, when the open floor plan style became popular, so many of those walls and doors segmenting the house suddenly fell into disfavor.

Today, few homeowners want a highly segmented house. What if you want to eliminate some of those walls altogether? Opening up rooms by removing walls is one of the most coveted home improvement projects. It's a project that returns instant value to the homeowner. As soon as the surrounding area is patched and painted, you can start enjoying your new open space. Larger, unsegmented rooms modernize older homes and nearly always result in greater home resale value.

Like additionsit's a project that is uniformly liked. Often with additions, their towering cost is not realized in resale. But when you open up a room and you do it on a do-it-yourself basis, materials are so inexpensive that resale usually will far exceed total cost.

As long as the wall you intend to remove is not load-bearing, you can take it down with little thought toward structural support of adjoining spaces. Structurally, the wall exists on its own. Replacing a load-bearing wall with a support beam requires surprisingly few materials. This project is more about labor than materials. If you live in a condominium, you may need to secure permission from the association board before you begin the work.

It is nearly guaranteed that you will need a building permit to replace your wall with a support beam. Is your support beam sufficiently sized for the opening? Plumbing or electrical services likely run through the wall.

Shut off the electrical circuit breakers, then check with a voltage detector. Electrical wires will need to be addressed.

Most likely you will have at least a couple of outlets and a light switch or two that you will need to relocate.

In many cases, it is a matter of moving existing wiring to a different portion of the wall or to a new wall. If you feel even the slightest bit uncomfortable with electrical work, hire an electrician. Costs can vary dramatically according to your area and local contractors. Hiring a contractor means that you get multiple workers attacking your job, saving considerable time.

The type of work is not complicated, but there is considerable lifting of heavy materials, especially when it comes time to fit the support beam in place. The contractor will have immediate access to a support beam from a supply house or the contractor can build one from scratch. All of the other lumber is purchased off the shelf at your local home improvement store. Whatever you remove in a wall must be replaced temporarily.

When you remove a load-bearing wall, you need to create an adjacent support system of equal or greater strength prior to removal that will continue to bear the weight until the beam is fully in place. There are either of two ways to accomplish this:. In either case, provide supports at the ceiling and the floor for the posts to rest against or else these posts may punch through the ceiling.

Use a stud finder to place the top of the support squarely under the joists. Light swings of the hammer will punch clean holes in the drywall. A line of these holes will allow you to pry back the drywall.
