This online Beam Calculator is engineered to evaluate critical parameters of floor and support beams in construction projects, including bending moments and shear forces. This tool provides a comprehensive load and strength analysis that ensures structural reliability under various conditions, delivering precise and efficient calculations.

Key functionalities of the Beam Load and Strength Calculation Calculator include:

  • Computation of beam strength considering both distributed and concentrated loads.
  • Selection among various support conditions, such as hinged joints or fixed supports.
  • Specification of cantilevers on either side of the beam.
  • Load determination using versatile measurement units, including kilograms, meters, newtons, or kilonewtons.
  • Graph plotting of bending moment and shear force diagrams with color indication for positive and negative values.

Steps for using the Beam Calculator:

  1. Enter the span length between the supports.
  2. Select the boundary conditions (hinged joint or fixed support).
  3. If applicable, specify the dimensions of any cantilevers.
  4. Define the distributed load by specifying its magnitude and area of application.
  5. Add concentrated forces as needed, indicating multiple points of application.
  6. Input the values for any concentrated moment along with its corresponding distance.

The calculation results include detailed bending moment and shear force diagrams, which help visualize the load distribution along the beam. With the flexibility to choose any measurement units, this calculator is suitable for use in international construction projects.
