The Non-Linear module adds to the program a long series of non-linear elements and hinges, in order to perform static and dynamic analyses.

A large variety of springs is available:

  • gap and hook;
  • bi-linear and tri-linear plastic laws;
  • Pivot, Tomazevic-Lutman and ring-shape rules;
  • symmetrical and unsymmetrical slip-type laws;
  • and more…


Non-linear hinges, part of this module, are highly customizable. Through the simple scripting engine already available for verifications, hinges can be set-up with user-defined values, even with interaction domain between shear/moment and axial force.
