Frame section behavior

The frame section behavior:

  • requires definition of the section's shape and its material response;

  • uses linear elastic behavior in the interior of the frame element;

  • can include “lumped” plasticity at the element ends to model the formation of plastic hinges;

  • can be uniaxial only, with response governed by a phenomenological buckling strut model, together with linear elasticity and tensile plastic yielding; and

  • for pipe sections only, can switch to buckling strut response during the analysis.
