## Calculating Force on a Truss Connection Joint

• Calculates the force and stress on connection joints
• Used in truss design, joints, and buckling
• Incorporates in-line programming and error checking (with the “if” function)

This worksheet using PTC Mathcad helps you to calculate the force and pressure on a connection joint within the specified dimensions of the joint for a particular material, and under particular trusses and weld lengths. Given the geometry of the connector and the material properties, this worksheet demonstrates how to determine whether the force on the joint will cause buckling.

You can modify this worksheet and adjust it to fit your own needs by entering:

• The connection yield strength
• The diameter of the base
• The diameter of the riser
• The height of the riser

This worksheet includes step-by-step instruction on how to calculate for the force on the joint, the pressure on the joint, and the allowable pressure before buckling.  All formulas are included along with an example and solution.
