4. B modeling#
4.1. Characteristics of modeling#
The characteristics of B modeling are the same as A modeling, except that the cable is modeled by 30 elements CABLE_GAINE with the adherent case of the CABLE_GAINE_FROT law (TYPE_ “ADHERENT”).
The cable meshes are SEG3.
4.2. Calculation steps and functionalities tested#
The steps are the same as for modeling A. All features are tested with CABLE_GAINE elements.
4.3. B modeling results#
4.3.1. Displacements of the girder nodes#
The values extracted from field DEPL from STAT_NON_LINE are compared to the theoretical reference values. The tolerance for relative deviation from the reference is equal to:
3% for node \(\mathrm{NB010527}\);
1% for the nodes \(\mathrm{NB030127}\), \(\mathrm{NB050127}\), and \(\mathrm{NB050527}\);
0.1% for the other nodes.
