4. B modeling#

4.1. Characteristics of modeling#

We use a POU_D_EM model. The law of behavior of concrete fibers is MAZARS_UNIL. The law of behavior of steel fibers is VMIS_CINE_GC.

4.2. Characteristics of the mesh#

The mesh contains an element of type SEG2. The section of the beam is composed of a concrete fiber and a steel fiber.

4.3. Tested sizes and results#

The axial response of the beam and the experimental results are presented.
