This online beam calculation tool is designed to determine key parameters of a floor beam, such as bending moment and shear force. These values are essential for structural strength analysis and ensuring the reliability of the structure under various load conditions. The calculator allows for accurate load calculations on the beam, providing convenience and speed in performing calculations.

Calculator functionalities:

  • Beam strength calculation considering distributed and concentrated loads.
  • Selection of various types of support conditions, such as hinged joints or fixed supports.
  • Ability to specify cantilevers on both sides of the beam.
  • Load determination in any measurement units, including kilograms, meters, newtons, or kilonewtons.
  • Graph plotting of bending moments and shear forces with color indication of positive and negative values.

Steps for using the calculator:

  1. Enter the span length of the beam (between the supports).
  2. Select the boundary conditions (hinged joint or fixed support).
  3. If necessary, specify the dimensions of the cantilevers.
  4. Define the distributed load by specifying its magnitude and area of application.
  5. Add concentrated forces, if necessary, specifying multiple points of application.
  6. Set the values of the concentrated moment and the distance to it.

The calculation results include bending moment and shear force diagrams, helping visualize the load distribution across the beam. For ease of use, the calculator allows selecting any measurement units, making it suitable for international use.
