Selecting Sawn-Timber Beams

Part of the VNR Structural Engineering Series book series (VNRSES)


Structural members stressed primarily in bending are called beams. Horizontal beams of dimension lumber, such as 2 × 8s, used repetitively in bending are usually referred to as joists, whereas large beams that support other beams are called girders. Beam sections are generally chosen on the basis of bending and then checked for other possible failure modes. Beam failure could be a result of bending, shear, lateral buckling, bearing, deflection under service loads, or deflection from creep or ponding. Beam design consists of selecting a species, grade, and cross-sectional dimensions to prevent any of these types of failure from occurring.
