Use the Wendrick Truss Calculator to determine the forces within a truss structure based on various inputs. This tool is useful for engineers and designers working on structural analysis and design.

Truss Calculation Formula

The Wendrick Truss Calculator uses specific formulas to determine the forces within a truss structure based on its type and dimensions. This includes calculating the reaction forces and internal forces based on load application and truss geometry.

Forces = Load / Span Length

Variables:

  • Forces are the internal forces within the truss members (lbs)
  • Load is the total load applied to the truss (lbs)
  • Span Length is the distance between supports of the truss (ft)

To calculate the internal forces, you divide the applied load by the span length. This simple formula helps in determining the forces in different truss configurations.

What is Truss Calculation?

Truss calculation refers to the process of analyzing the forces within a truss structure. This involves determining the internal forces in each member of the truss based on applied loads and truss geometry. Accurate truss calculations are crucial for ensuring structural integrity and safety in engineering design.
