Calculating 3D Trusses with FEM
The finite element method (FEM) is used for calculations on planar trusses.
Unlike rigid body calculations, the trusses here can also be statically indeterminate.
Bar forces, support reactions, and the displacement state are calculated.
The user can save their entered model data locally.
To the Results
The results section calculates the displacement state of the truss and displays the truss in its deformed state.
For graphical representation, all displacements are uniformly enlarged so that they can be seen.
The truss members are color-coded as tension members (blue), compression members (red), and zero-displacement members (white).
Clicking on a member in the results display shows the corresponding axial force.
Clicking on a node in the results display shows the corresponding displacements.
