Glulam beam span

What is the difference between LVL and glulam? What are glulam timbers and how they are used? These tables are provided as a guideline. AITC Beam Capacity Tables. Glulam Beam Calculator.

The beam span length is fixed for this demo version. The full version allows you to design beams of any size. Table specifications are provided with each table indicating conditions and assumptions used to calculate the loads.

Stock beams, manufactured in common dimensions, are cut to length when the beam is ordered from a distributor or dealer. Balanced members are symmetrical in lumber quality from the horizontal centerline, out. Balanced beams are used in applications such as cantilevers or continuous spans , where either the top or bottom of the member may be stressed in tension due to service loads.

By laminating a number of smaller pieces of timber, a single large, strong, structural member is manufactured from smaller pieces. The tables include values for section properties and capacities and allowable loads for simple span and cantilevered beams. A wide array of appearance options and layups make this one of the most versatile engineered wood products available. You can also use the Wood Beam Calculator from the American Wood Council website to determine maximum rafter and joist lengths.

Use the span tables below to determine allowable lengths of joists and rafters, based on size and standard design loads. The Glued Laminated Beam Design Tables, Form S47 provide recommended preliminary design loads for two of the most common glulam beam applications: roofs and floors. ENGINEERED WOOD PRODUCTS (EWP) LVL SPAN AND SIZE CHARTS. For builders, this translates to lower installed costs and more efficient framing.

The numbers in gray indicate the distance between the support posts. Dimensional Lumber Deck Beam Span Chart. Design a beam depth based on the rule of thumb for estimating the depth of manufactured beams which is to divide the span by 20.

When supporting joists that span feet with no overhang beyond the beam , a double ply beam can span in feet a value equal to its depth in inches. It also means that designers and builders have virtually unlimited design flexibility when using glulam , whether the application is home construction, a commercial warehouse roof or a highway bridge. Treated glulam beams are pressure treated with a Hi-Clear II, a clear industrial wood preservative.

That means glulam beams can span long distances with minimal need for inter-mediate supports. It leaves a light honey color finish that is virtually undetectable to the naked eye. It is intended for above ground exterior applications and is most common for raised deck beams. In addition to stamping the beam with the APA EWS trademark signifying that the member has been manufactured in accordance with the provisions of ANSI Standard A190.

Our glulam operations are 1 vertically integrated for supply of raw materials with all fiber sourced internally from Canfor’s sawmills located throughout the Southeast United States.

South (El Dorado, Arkansas and Washington, Georgia). Glulam has high structural capacity and is also an attractive architectural building material. Glulam is commonly used in post and beam , heavy timber and mass timber structures, as well as wood bridges.

The distance over which a wood beam bears a load when used for support is its span. The span of any wood beam depends on many factors, such as type of woo weight of the load and overall size of the beam. Calculating the span of a beam requires using various factors that you need to first determine for a structure where the beam is being used.
