4. Synthesis

The results obtained are validated by comparison with a reference analytical solution with very good precision.

The specific functionalities tested are as follows:

• operator DEFI_MATERIAU: definition of the characteristic parameters of steel and concrete materials allowing the calculation of the tension along the prestress cable, according to the rules of BPEL;

• operator DEFI_CABLE_BP: calculation of the tension along the cable and the coefficients of the kinematic relationships between the degrees of freedom of the cable nodes and the degrees of freedom of the « neighboring » nodes of the concrete beam;

• operator AFFE_CHAR_MECA: definition of a RELA_CINE_BP load;

• operator STAT_NON_LINE, option COMPORTEMENT: calculation of the equilibrium state taking into account the load type RELA_CINE_BP.
