StructureCalcs provides a free online beam calculator to analyze continuous and simply supported beams with unlimited spans, supports, and loads, computing shear force, bending moment, and deflection diagrams using the direct stiffness method. It supports over 2,600 steel sections across six international standards (AS4100, AISC, EN10365, BS4, JIS, IS808) or custom properties, with results updating in real time in the browser and no data sent to a server, and users can save models or export PDFs. The tool accommodates fixed, pinned, and roller supports and a range of load types, delivering interactive diagrams and explanations of the direct stiffness theory.
