Trussbeck: Structural Analysis

Understand the load path, then follow the calculation. Trussbeck is an offline structural analysis app: beam analysis with solutions, truss analysis and frame analysis, built for students and engineers.

From model to diagrams
Start with a template or build a 2D model. Set supports, point forces, moments and distributed loads. Inspect axial force, shear force and bending moment diagrams, support reactions and deflection. Move the cut to read values at a chosen position, including either side of a jump.

See how the answer is obtained
This beam analysis with solutions walks through equilibrium equations, the method of joints or sections, the force method and the three-moment equation where applicable. The direct stiffness method provides the numerical solution and a cross-check for the teaching steps. Frame analysis includes member forces and the deflected shape; truss analysis distinguishes tension and compression.

Explore sections and load cases
Enter dimensions for I/H sections, channels, angles, tubes and other parametric shapes. Compute area A, second moment of area I and section modulus W from your dimensions. Organize load cases and load combinations with factors you enter yourself. Change supports, loads or section properties and compare two variants.

Keep an analysis record
Use Trussbeck to draw shear and moment diagrams, then export a PDF analysis report with inputs, diagrams and solution steps. Choose units and the diagram sign convention to match your coursework or working method.

Model limits
For study and preliminary analysis. Results depend on your inputs and a first-order, linear-elastic, small-displacement model. This is not a design check against building codes. Buckling, dynamics and plastic behavior are not checked. Have real structures independently designed and checked by a qualified engineer.
