About

This Free Structural Frame Calculator will generate and find the bending moment and shear force diagrams of a 2D frame structure. The free version allows you to input frames with a maximum of 3 members with applied point loads and moments for 2D frame analysis. You can also control settings such as units, display settings of framing members and nodes etc. by simply clicking the ‘Settings’ button.

The SkyCiv Free Frame Calculator is part of our Structural Software that allows users to apply loads to a structure and interpret the results in an easy and clean diagrams. To fully utilise the power of SkyCiv Structural 3D Software, check out our Professional Plan. Apart from unlimited members and loads, you can also select materials such as wood and steel to perform structural frame analysis – features that this frame calculator does not support. The Professional Plan also allows the user to save and load projects, saving much time in re-entering the frame structures!

The following structural frame calculator is available for free to use – please let us know if you have any questions or comments and we’ll be glad to help!

Your Free Online Structural Frame Calculator

The above free structural frame calculator can solve and produce frame bending moment diagrams and reaction forces at the supports, all for free! The software will perform a finite element analysis on your frame, based on the nodes and beam/column elements added. The frame moment diagram calculator is completely online and available anytime you need for free!

Frames are typically rigid end fixity members that generate a bending moment and shear force load within members. These frames have been simplified into 2D but are also restrained in the Z direction to prevent any stability issues during the static linear analysis. Note: we also include a free truss calculator if you need truss (pinned) members for a truss structure.

Steel Structure Calculator

Our 3D Structural Analysis Software supports multiple materials, allowing you to perform steel frame calculation or wood frame calculation by simply adding your materials and solve! However, for this free 2D frame calculator version, materials is not a factor as the bending moment and shear forces in the frame structure are usually independent of materials. Material properties primarily affect the deflection results, as the outcomes are influenced by the material’s Young’s Modulus.
