In a simply supported beam, the only horizontal force is the 5kN/m force, which when multiplied by the length of the member (L = 10) we get 5*10 = 50 kN. Since most homes have a Rake wood, which is usually 6-8 wide, you can add that width to the rise. Obviously this is just a simple example and more complex structures will require additional calculations to determine the reaction forces - for this we have a more detailed tutorial on how to calculate reaction forces in a beam. D = Total depth of the beam. Each wood species and grade has its own set of stiffness or design values, including bending stress, shear stress, tension and compression stresses, and modulus of elasticity. First, we must calculate the required or actual shear, which we denote as VVV, our beam needs to overcome using this equation: Then we determine its corresponding actual shear stress, fvf_\text{v}fv, on our beam by dividing the actual shear by the cross-sectional area, AAA, of our beam, as shown below: We can also combine these two equations, together with A=bdA = b\times dA=bd to directly calculate the shear stress using the shear stress formula, as shown here: Substituting the values we have in our example, we then have: Like with the bending stress, we also need to compare our actual shear stress with our beam's adjusted shear stress design value, which we denote as FvF_\text{v}'Fv. Im building a pole barn. Using the diagram below, measure your roof from the ground, and enter building dimensions into the calculator #2 above.
