Structural engineers
Study roof trusses, bridge trusses and frames; inspect member forces, support reactions and movement.
Structural analysis
Truss Lab
Build a truss or frame in 2D or 3D. Add supports and loads, then see the forces in each member and how the structure moves.
Who can use Truss Lab?

A truss, from model to results
A guided screen tour of a built-in bridge example: 2D setup, linear analysis, a 3D view and the results panel. Both 2D and 3D solver controls are available in the app; this tour runs the 2D solver.
Read the walkthrough
- Start with a 2D model and its supports and loads.
- Run a linear 2D analysis; inspect forces and movement.
- View the same model in 3D. This is a 3D view, not a separate 3D solve.
- Open the wider results panel to review member utilization.
What you can do with Truss Lab
See how your structure carries its loads.
- Interactive nodes, members, supports and load cases
- 2D and 3D structural solvers
- Member forces, reactions and displacement results
- Stiffness matrix and equilibrium inspection
The working sequence
- 01
Draw or choose a truss or frame. Enter member sizes and materials.
- 02
Set the supports, add the loads and choose the analysis method.
- 03
Run the analysis and see member forces and how the structure moves.
- 04
Check the model and warnings, then use the available exports.
Before you use the results
Review model stability, element formulation, material properties, loading and solver diagnostics before applying results to a project.
