Structural ability of sawn- and engineered-wood beams are predicted through mathematical calculation. Formulas that determine the allowable span and size of a beam rely on a host of variables like species, grade, size, deflection limit and type of load.
AITC Beam Capacity Tables. AITC Capacity Tables provide the uniformly distributed load that a glued laminated timber beam can support based on beam size, span, and material properties. Table specifications are provided with each table indicating conditions and assumptions used to calculate the loads. These tables are provided as a guideline.
The Glued Laminated Beam Design Tables, Form S475, provide recommended preliminary design loads for two of the most common glulam beam applications: roofs and floors. The tables include values for section properties and capacities and allowable loads for simple span and cantilevered beams.

• Floor joists either lap or butt on top of beam, or frame into beam with hangers. • Beam Span is valid for simple span beams and continuous, equal span beams. • 3" bearing length is required at end supports.
Tables providing size selections for various beam spans and loading combinations for Southern Pine dimension lumber and Southern Pine glued laminated timber are available for the following applications:
On longer spans the beam may require much more bearing space as indicated by this table. Fastening Beams of more than one ply must be fastened together with either nails or bolts.
A complete analysis of wood's mechanical properties is complex, but understanding a few basics of lumber strength will allow you to size joists and rafters with the use of span tables. Let's start by taking a broad view.
Use the span table to find the thickness and depth of the engineered wood piece that should be used for your building project. The proper size will be sorted under total and live load per foot values.
Unlike other engineered wood products our glulam beams are able to accept many different types of treatment. Common Uses of Timber TEchnologies Glulam Beams Rafters

Use the Simple-Span Floor Joists table where the floor joists frame into the side of or end on top of the header. 2. Rough Opening is the clear span of the header, equal to the door or window rough opening, and is valid for simple and equal, continuous header spans.
To increase the use of wood by assuring the broad regulatory acceptance of wood products, developing design tools and guidelines for wood construction, and influencing the development of public policies affecting the use and manufacture of wood products.
An engineered wood beam is a wood product or assembly designed to replace traditional structural lumber. The engineered product is stronger and allows for greater spans. Sizing engineered wood beams is not at all difficult. The easiest way to size engineered wood beams is to use the span tables that ...

Because of the predictable spanning and load-bearing capabilities of engineered wood beams, builders, designers, architects, and engineers have made them a common framing component in buildings with wide open spaces and big daylight openings.
Add strength and reliability to your structure when you use Parallam® PSL beams. The superior strength of Parallam® PSL makes longer spans possible, giving you more design options with open, spacious floor plans.
