1 Presentation
The structure of data
cabl_precont
is produced by the operator
DEFI_CABLE_BP
[U4.42.04]. This
operator calculates the initial profiles of voltage along the cables of prestressed of a structure
concrete, knowing the voltage 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 the 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
the operator
STAT_NON_LINE
[U4.51.03], option
COMP_INCR
.
The structure of data
cabl_precont
gather a table, an elementary card (card of
initial stresses) 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).
