4. B modeling#
4.1. Characteristics of modeling#
The modeling is 3D for the concrete ring and CABLE_GAINE for the cable. The modeling for the cable is of the “ADHERENT” type.
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 \({10}^{6}N\) without anchor recoil.
In a second phase, a \(\mathit{DY}=-\mathrm{0,1}\) move is imposed on the group of nodes ANCR2.
4.2. Characteristics of the mesh#
The mesh contains 20 elements of type HEXA8 and 20 elements of type SEG3.
4.3. Tested sizes and results#
We test the results using the references obtained in modeling A, we thus verify that models BARRE and CABLE_GAINE/ADHERENT give the same results.
The order number 2 corresponds to the end of the first phase (CALC_PRECONT) and the order number 3 to the end of the second phase (move \(\mathit{DY}=-\mathrm{0,1}\) to the group of nodes” ANCR2 “).
Mesh \(\mathit{M89}\) is the first mesh of the cable starting from ANCR1.
