However, by inspecting our formulas, we can also say that the beam's length also directly affects the deflection of the beam. Self-weight of the plate has been ignored and should be taken into account in practice. Basically, it's the amount of displacement or bending that a beam experiences when subjected to a load. by mobile, BHT thank you for reporting in this error. The method of calculation is somewhat different from the BS 8110 Part 1. An interactive drawing area allows you to design complex, multi-span beams in minutes. Beam deflection is when a beam bends or sags under its own weight or due to applied loads.
