At a 4-feet span, a #1-S-P-F 66 can support 1,040 pounds per linear foot (PLF) or 4,160lbs per span, and a DF-L D-SS can carry 2080 PLF or 8320lbs per span based on allowable bending stresses (Fb). The first step is the same for sawn- and engineered wood materials: add up all the loads acting on a header or beam and then translate this load into terms of how much load each lineal foot of header or beam will feel. These parameters are the beam's allowable deflection, bending stress, and shear stress. Multiply the loading per square foot by the area in square feet of the surface which the beams will be supporting. The total load is 4,000 pounds. Beam deflection is when a beam bends or sags under its own weight or due to applied loads. You'll also see a note if your wood beam passed the deflection test. For the last parameter we want to check in this calculator, we'll find the actual shear stress due to the beam loading and compare that to our beam's adjusted shear stress design value. For example for CDC_\text{D}CD: Please refer to the NDS for Wood Construction for the other adjustment factors. from there it slowly declines or stays the same. Roof Pitch Calculator Results Explained. For such cases, we should choose either a different wood species, commercial grade, or a larger beam size, then perform the wood beam deflection calculation again. Required fields are marked *.
