3. Modeling A

3.1. Characteristics of modeling

Modeling POU_D_TGM

Breakdown: 10 elements in the column and in the beam

3.2. Characteristics of the mesh

Number of knots: 21

Number of meshes and types: 20 SEG2

3.3. Characteristics of the cross section mesh

Number of fibers: 100 (divided into 10 on each side)

Number of meshes and types: 100 QUAD4

3.4. Tested sizes and results

The results are obtained by an automatic division of the time step and with arc-length control of the overall displacement response of the structure.

3.5. notes

Using the arc-length technique makes it difficult to define the reference value to be entered in the TEST_RESU command, since these values cannot be imposed. The tests were therefore done in reverse by choosing the displacement values as a parameter and the force value as the tested value (i.e. ETA_PILOTAGE).

It is this way of testing that explains the high differences observed in \(\mathit{DY}\) at the last moments when the curves are superimposed perfectly.
