composite wood beam spans

Span Tables Tutorial - American Wood Councilwood is naturally engineered to serve as a structural material: The stem of a tree is fastened to the earth at its base (foundation), supports the weight of its branches (column) and bends as it is loaded by the wind (cantilever beam). 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. The structural goal of a house is to safely ...

AITC Glulam - Beam Capacity TablesAITC 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. Specific beam designs should be reviewed by a licensed design professional. These tables are free downloads that require the

Span Tables - Southern PineHeaders & beams. Simplified span tables for Southern Pine lumber and glued laminated timber (glulam) headers, beams and girders. View Size Selection Tables · View Allowable Load Tables. Disclaimer: These easy-to-use tables were compiled by the Southern Forest Products Association (SFPA) as a service to design/build professionals and other Southern Pine users. Reference design values are for normal load duration under the moisture service conditions specified.

Glulam - APA The Engineered Wood AssociationPound 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 beams and headers in residential construction to soaring arches for domed roofs spanning more than 500 feet. Glulam is a stress-rated engineered wood beam composed of wood laminations, or "lams", that are ...

Wood vs. Engineered Lumber | Professional BuilderAdditional benefits are related to ease of installation, dimensional stability, and structural integrity of engineered products. "Engineered wood products actually improve upon many of the inherent structural advantages of wood," adds Merry. "Cross-laminated plywood and oriented strand board, for example, distribute loads along-the-grain strength of wood in both panel axes. Glulam beams and wood I-joists can carry greater loads over longer spans than is possible with solid sawn ...
