Beam Span Calculator

The SkyCiv Beam Calculator is a free online tool for analyzing beam behavior. Users enter a beam length, select support types, and define cross‑section properties to generate reactions, shear force diagrams, bending moment diagrams, deflection, and stress outputs. The calculator handles common setups such as simply supported and cantilever beams, and the free version is accessible without a paid plan. Results are presented as diagrams and numerical values that can be used for design checks or verification of structural calculations. The platform also provides links to additional SkyCiv resources, such as a Section Builder for custom shapes and video tutorials to guide users through the workflow. While the free tier offers core analysis capabilities, optional signup unlocks more advanced platform features. The tool is designed to streamline the beam calculation process from input to compliance checking. The calculator generates reactions, shear force and bending moment diagrams, deflection, and stress for cantilever or simply supported beams. Users input beam length, select support types from a menu, and define section properties such as Moment of Inertia or Young's Modulus. The interface includes options to use SkyCiv's integrated Section Builder Tool for preset or custom shapes. A video tutorial and written step‑by‑step instructions walk users through the calculation workflow, from defining geometry to viewing design code compliance. The free version is accessible without requiring a paid plan, making it suitable for quick analyses or learning structural behavior.
