How Do You Calculate Deflection Of An I-Beam?
An I-beam is a type of beam commonly used in the construction of steel buildings and structures. Its cross-section forms the shape of an I, hence its name. The deflection of an I-beam is defined as how much it bends when a load is applied to it, measured from its original position to the lowest point. You can calculate the deflection of an I-beam using relatively simple equations. Gather the following information about your I-beam and its load: Q–Uniform Load (N/mm) F–Point Load (N) L–Length of Beam (mm) I–Moment of Inertia (mm4) E–Modulus of Elasticity (N/mm2)) Y–Perpendicular distance from neutral axis (mm) The latter three values are inherent properties of the I-beam which vary depending on its size. Find the corresponding values of your I-beam in the table listed in the resources section. Substitute your values into one of the following equations. If your beam has a distributed load, use δ = (5 q L4) / (E I 384). If your beam has a point load, use δ = (F L3 )/( E I 48), where
