![]() ![]() ![]() Sawn-Lumber span tables are convenient tools. Technical experts have computed many combinations of these variables and present a variety of solutions in the form of span tables. You can do these calculations yourself or you can use span tables. 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. Structural ability of sawn- and engineered-wood beams are predicted through mathematical calculation. No matter what material we specify, beams must provide adequate strength, stiffness, and shear resistance. We will compare the performance and cost of sawn-lumber, LVL, Timberstrand, Parallam and Anthony Power Beam in several different applications. We know how to measure the forces acting on a beam, now we’ll use this information to choose the appropriate structural material to resist the loads. In Part 1, “ Calculating Loads On Headers and Beams“, we learned how to trace load paths and translate roof, wall and floor loads into pounds per lineal foot of supporting beam. Once the loads acting on structural beams are calculated, the next step is to size and select the appropriate beam. Some information contained in it may be outdated.
