9. G modeling#

9.1. Characteristics of modeling#

The modeling is Q4GG for the concrete ring and CABLE_GAINE for the cable.

Three calculations are carried out, in all cases, the linear friction is taken to be equal to \(\mathrm{0,01}\) and the curved friction to \(\mathrm{0,03}\).

  1. For the first calculation (EVOLNOLI), the cable is of type PASSIF/ACTIF: PASSIF to the group of nodes” ANCR1 “and ACTIF to the group of nodes” ANCR2 “. Charging is carried out in two stages. Initially, the cable is prestressed with CALC_PRECONT and a tension of \({10}^{6}N\) without anchor recoil. In a second step, a \(\mathit{DY}=-\mathrm{0,1}\) move to the group of nodes” ANCR2 “is then imposed.

  2. For the second calculation (EVOLNOL2) the cable is of type ACTIF/ACTIF. The cable is prestressed with CALC_PRECONT and a tension of \({10}^{6}N\) without anchor recoil.

  3. For the third calculation (EVOLNOL3) the cable is of type ACTIF/ACTIF. The cable is prestressed with CALC_PRECONT and a tension of \({10}^{6}N\) with an anchor setback of \(5\times {10}^{-4}m\).

9.2. Characteristics of the mesh#

The mesh contains 20 elements of type QUAD4 and 20 elements of type SEG3.

9.3. Tested sizes and results#

The reference values are analytical and presented in § 2.2.2.
