Open Web Roof Truss Span Table

Of bearings and is based on uniformly loaded joists.

Open web roof truss span table.

The shapes and spans shown here represent only a fraction of the millions of designs produced by alpine engineers. Whether your project is for retail or office space a school multi family apartments condos assisted living facilities hotels and motels warehouses you name it an open floor plan is often a primary requirement. The spans are based on simple span joists. Floor truss span chart each individual floor truss design is unique based on multiple variables.

Included are a series of representative roof truss span tables that will give you an idea of the truss spans available for a particular load condition load duration lumber type and truss configuration. Tcll 40 psf tcll 80 psf tcll 125 psf truss spacing truss spacing truss spacing. Basic lumber design values are f 2000 psi f 1100 psi f 2000 psi e 1 800 000 psi duration of load 1 00. Span tables below illustrate common combinations of the multiple variables available.

Redbuilt open web trusses offer a variety of solutions for a broad range of challenges. Geometry loading spacing bearing conditions etc. The maximum span is measured o c. Spacing of trusses are center to center in inches.

Alpine truss designs are engineered to meet specific span configuration and load conditions. You can use sbca s span charts to roughly determine truss sizes available.
