SkyCiv Free Beam Calculator

SkyCiv’s free beam calculator runs in the browser and analyses a simply supported or cantilever beam. You set the supports, apply up to two point loads, two distributed loads (uniform, triangular or trapezoidal) and two moments, and get reactions, shear force and bending moment diagrams, deflection and stress. It suits a quick beam check, students verifying a hand solution and a first estimate on site. Limitation: the free version takes only the material’s Young’s modulus; step-by-step hand calculations, code checks and steel, timber and concrete design are in the paid software.
