What is the best way to consider fiber concrete with the RFEM structural analysis program?

Answer

With the 'RF-MAT NL' add-on module, it is possible to use the nonlinear material model 'Isotropic Damage 2D/3D' in RFEM to define the stress-strain curve for the steel-fiber concrete. The internal forces and the deformation can be determined in the subsequent nonlinear FE calculation.
