CSICOLMaterial Properties and Models

There are several stress strain curves to choose from and apply to any shape in the cross-section. Different stress-strain relationships can be assigned to different shapes in a single cross-section. Use different stress curves to model various materials and properties, from simple linear and rectangular stress blocks to parabolic curves. Different stress-strain curves to model reinforcing bars varying from elastic only to complex strain-hardening models. The stress-strain relationships include:

  • ACI Whitney Rectangle, CSA Parabola and PCA Parabola;
  • Elasto-plastic and strain hardening models for rebar steel.
