3. Modeling A

3.1. Characteristics of modeling

The modeling is 3D for the concrete ring and BARRE for the cable.

The cable is of type PASSIF/ACTIF: PASSIF to the group of nodes ANCR1 and ACTIF to the group of nodes ANCR2. The linear friction BPEL is taken to be equal to \(\mathrm{0,01}\) and the curved friction to \(\mathrm{0,03}\).

In a first phase, the cable is prestressed with CALC_PRECONT and a tension of \({10}^{6}N\) and without anchor recoil.

In a second phase, a \(\mathit{DY}=-\mathrm{0,1}\) move is imposed on the group of nodes ANCR2.

3.2. Characteristics of the mesh

The mesh contains \(20\) elements of type HEXA8 and 20 elements of type SEG2.

3.3. Tested sizes and results

The results tested are of the non-regression type to serve as a reference in the B modeling and concern the displacements and the tension in the cable (see values in § 4.3).
