Shear Force, Bending Moment Diagram & Deflection Calculator

The Shear Force, Bending Moment Diagram & Deflection Calculator helps engineers generate beam diagrams for common loading and support conditions used in structural analysis.

The tool supports simply supported beams, fixed beams, propped cantilevers, cantilever beams, and overhanging beams with uniformly distributed, triangular, trapezoidal, partial, and point loads.

By entering span length, load intensity, point load position, material modulus, and moment of inertia, the calculator produces load, shear, bending moment, and deflection diagrams with detailed tabulated results.

Key Features

• Generates shear force diagrams and bending moment diagrams
• Supports simple, fixed, cantilever, propped, and overhanging beams
• Includes point load, UDL, UVL, trapezoidal, and partial load cases
• Calculates support reactions, maximum shear, and maximum moment
• Provides deflection diagrams where material properties are entered
• Includes a downloadable PDF report for design documentation

Applications in Structural Design

This calculator is useful for preliminary beam design, hand calculation checks, structural analysis verification, and engineering education. It helps visualize internal force distribution before detailed member design.

Engineering Note

Sign conventions for shear, moment, and deflection diagrams should be reviewed against the selected reference method before final design use. Critical structural designs should always be verified by a qualified engineer.
