What is a Truss Calculator?

A truss calculator is an engineering tool used to analyze the structural behavior of truss systems. This free online truss analysis calculator helps engineers, students, and professionals calculate member forces, support reactions, and joint displacements in 2D truss structures.

How to Use This Truss Analysis Tool

Step 1: Define Your Structure
Start by adding nodes (joints) to your truss. Click “Add Node” and position them on the canvas. Mark support nodes as fixed or roller supports.
Step 2: Connect Members
Add members (beams) to connect your nodes. Each member represents a structural element in your truss system.
Step 3: Apply Loads
Add forces to specific nodes. You can apply vertical loads, horizontal loads, or both. Forces are measured in Newtons (N).
Step 4: Analyze Results
Click “Analyze Truss” to calculate member forces. Results show tension (red) and compression (green) forces with exact values.
