F modeling
==============


Characteristics of modeling
-----------------------------------

The modeling is DKT 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 :math:`\mathrm{0,01}` and the curved friction to :math:`\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 :math:`{10}^{6}N` without anchor recoil. In a second step, a :math:`\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 :math:`{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 :math:`{10}^{6}N` with an anchor setback of :math:`5\times {10}^{-4}m`.


Characteristics of the mesh
----------------------------

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


Tested sizes and results
------------------------------

The reference values are analytical and presented in § :ref:`2.2.2 <RefNumPara__24718_2055105839>`.
