FRAME3DD is a program for the static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness.


  • Comprehensive documentation with numerous example files
  • Multiple load cases in each analysis with gravity loading, partial trapezoidal loads, thermal loads, and prescribed displacements
  • Matlab and spreadsheet interface, graphical ouput via Gnuplot
  • Packages for Windows, OS X and Linux
  • Shear deformation effects on geometric stiffness are included

  • Very easy to set up and it works very well. Overall it looks like really excellent work. I can't work out how to do a feature request so I'll put mine here. It would be great if you could model end releases without having to insert low stiffness members to simulate the effect. I can see its in the todo list. This would make modelling trusses much much easier. Kind regards

  • small and efficient and gets the job done.
