1 Presentation

The structure of data cabl_precont is produced by operator DEFI_CABLE_BP [U4.42.04]. This
operator calculates the initial profiles of tension along the cables of prestressed of a structure
concrete, knowing the tension applied at the ends and other parameters characteristic of
anchorings and of materials. Each cable is defined by an occurrence of the key word factor
DEFI_CABLE.

The structure of data cabl_precont is then used by operator AFFE_CHAR_MECA
[U4.44.01], in order to define a mechanical loading of type RELA_CINE_BP, with an aim of calculating
the state of balance of the unit structure concrete/cables of prestressing. The resolution is carried out by
operator STAT_NON_LINE [U4.51.03], option COMP_INCR.

The structure of data cabl_precont gathers a table, an elementary card (card of
initial constraints) and a list of relations (relations kinematics between the DDL of the nodes of
cables and DDL of their nodes “close” to the structure concrete).
