Can a 2x12 span 16 feet?
A 2×12 (2-by-12) floor joists can span up to 23 feet 3 inches, 2×10 (2-by-10) up to 19 feet 1 inches, 2×8 (2-by-8) up to 15 feet & 2×6 (2-by-6) up to 11 feet 4 inches at 16″ spaced by using southern yellow pine graded as #1 when live load of 30 lbs/ft^2 & dead load of 10 lbs/ ft^2.
How do you calculate beam size?
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 12-foot room and supporting a weight of 600 lbs., the maximum bending moment would be 12 x 600/8 = 900 foot-pounds.
What are the 3 grades of glulam?
1 they are referred to as glulam appearance "grades"). The classifications are as follows: Framing, Industrial, Architectural, and Premium. These classifications are summarized below and relate to a glulam beam's appearance only, not to its strength.
Is glulam stronger than LVL?
The laminated beam is stronger but more expensive and used when bigger cross-sections are required. Generally made from hardwood, rather than the lvl softwood.
What is glulam beam?
Glulam is a stress-rated engineered wood beam composed of wood laminations, or "lams", that are bonded together with durable, moisture-resistant adhesives. The grain of the laminations runs parallel with the length of the member. Glulam is versatile, ranging from simple, straight beams to complex, curved members.
What is a glulam product guide?
The Glulam Product Guide, Form X440, describes APA trademarked glulam, addresses important design considerations and includes a specification guide. It also highlights some of the many applications where glulam is used in construction.
What is the standard beam width?
Typical stock beam widths used in residential construction include: 3-1/8, 3-1/2, 5-1/8, 5-1/2, and 6-3/4 inches.
Is glulam stronger than steel?
Glulam Basics. Glued laminated timber, or glulam, is a highly innovative construction material. Pound for pound, glulam is stronger than steel and has greater strength and stiffness than comparably sized dimensional lumber. Increased design values, improved product performance, and cost competitiveness make glulam the superior choice ...
What are the dimensions of glulam?
Typical stock beam widths include: 3-1/8, 3-1/2, 5-1/8, 5-1/2 and 6-3/4 inches.
How thick is glulam?
Individual lams typically are 1-3/8 inches thick for southern pine and 1-1/2 inches thick for Western species , although other thicknesses may also be used.
Is glulam lumber stronger than lumber?
With glulam, builders and specifiers can continue to enjoy the strength and versatility of large wood members with- out relying on the old growth-dependent solid-sawn timbers. Glulam has greater strength and stiffness than comparable dimensional lumber.
What is the standard beam width?
Typical stock beam widths used in residential construction include: 3-1/8, 3-1/2, 5-1/8, and 5-1/2 inches.
Do you need to use cosmetic repair on glulam?
Cosmetic repairs, such as applying elastomeric fillers, may help mask checks and improve beams' appearance but are typically not required. Since there are no limitations on the number of checks which may appear on the surface of a glulam, the use of cosmetic repairs is a contractor/owner decision.
Does glulam shrink?
Unlike large solid sawn or built-up timber beams, glulam will exhibit minimal shrinkage and warping , which ensures a level floor surface. In addition, due to the excellent fastener-holding capability of glulam, floors have minimal nail popping and fewer squeaks.
Construction
- Glued laminated timber, or glulam, is a highly innovative construction material. Pound for pound, glulam is stronger than steel and has greater strength and stiffness than comparably sized dimensional lumber. Increased design values, improved product performance, and cost competitiveness make glulam the superior choice for projects from simple beam...
Use
- Glulam has a reputation for being used in striking, exposed applications such as vaulted ceilings and other designs with soaring open spaces. In homes, churches, public buildings, and other light commercial structures, glulam is often specified for its beauty as well as its strength. It's also a workhorse in common hidden applications, including simple purlins, ridge beams, garage door h…
Design
- For non-residential applications, where long spans, unusually heavy loads, or other circumstances control design, custom members are typically specified. Common custom shapes include straight beams, curved beams, pitched and curved beams, radial arches, and tudor arches.
