Beam Deflection Calculator

The SkyCiv Beam Calculator is a free online tool that computes reactions, shear force, bending moment, deflection, and stress diagrams for cantilever and simply supported beams. Users input beam length, support type, and section properties such as moment of inertia and Young's modulus to obtain structural results. The site presents this as a free version of their professional beam analysis software, providing a streamlined workflow for basic beam calculations without requiring a paid subscription. Results include visual diagrams and numerical values for internal forces and deformations, allowing users to assess beam performance under various loading conditions. The interface guides users through a step-by-step process, making complex structural analysis accessible to those without specialized engineering software. The calculator explicitly states it is a free version of SkyCiv's Beam Analysis Software, offering core functionality at no cost. Compared to other free beam calculators, the SkyCiv version distinguishes itself through its integrated Section Builder Tool, which provides access to a global database of preset shapes or the ability to create custom sections. While other tools like Omni Calculator or MechaniCalc focus primarily on deflection or basic moment calculations, SkyCiv's offering includes comprehensive diagram generation (shear, moment, deflection, and stress) alongside material property inputs. The inclusion of design code compliance checking and video tutorials further sets this version apart, providing a more guided professional experience within a free pa
