Creation of meshes
~~~~

• Beam mesh (15 to 20 elements).

• Meshing the right section of the beam (20 to 25 elements in the height, 2 to 5 elements in the width).


Definition of fibers
~~~~

• Use the DEFI_GEOM_FIBRE [U4.26.01] command to define the multi-fiber cross section of the beam.

• Visualization of the fiber section with CREA_MAILLAGE [U4.23.02].


Definition of materials
~~~~

Define materials using command DEFI_MATER_GC [U4.42.07].


Data checks
~~~~

Visualize the right section of the multifiber beam with local landmarks.

Calculus
~~~~

Conduct the calculation as far as possible.

Changes in deformations:

• Deformations of stretched and compressed concrete.

• Deformations of tense and compressed steels.

Changes in constraints:

• Constraints of stretched and compressed concrete.

• Stresses of stretched and compressed steels.
