5. Errors and alarms#

5.1. Errors caused by inconsistency in input parameters#

A check of the consistency of the input parameters is performed at the start of the execution of command CALC_FERRAILLAGE. The calculation can be stopped by a fatal error in the following cases:

  • in the case BAEL91 to ELU: if the keywords GAMMA_S, GAMMA_C, FE or FCJ, are not entered;

  • in the case BAEL91 to ELS: if the keywords N, SIGS_ELS or SIGC_ELS are not entered;

  • in the case BAEL to ELS_QP: if the keywords ALPHA_E, FYK, FCK,,,,, SIGC_ELS_QP,, WMAX_INF/SUP (_Y/Z), KT, PHI_X /Y/Z_ INF/SUP are not filled in;

  • in the case EC2 to ELU: if the keywords GAMMA_S, GAMMA_CFYK or FCK, are not entered;

  • in the case EC2 to ELS: if the keywords ALPHA_E, SIGS_ELS, SIGC_INF/SUP (_Y/Z) _ ELSou FCK are not filled in;

  • in the case EC2 to ELS_QP: if the keywords ALPHA_E, FYK, FCK,,,,, SIGC_ELS_QP,, WMAX_INF/SUP (_Y/Z), KT, PHI_X /Y/Z_ INF/SUP are not filled in;

  • for all cases: if the value of the coating is greater than the thickness/height/width of the structural element.

As well as the following specific cases:

if* FERR_MIN = “OUI “** and the keywords RHO_LONGI_MIN and RHO_TRSNV_MIN are not entered.

if* FERR_SYME = “OUI “** and the keyword SEUIL_SYME is not entered.

5.2. Alarms issued during the calculation of bending steels#

The calculation of bending steels can emit one or more alarms in the following cases:

if the “1D” element or at least one facet of the “2D” element is in pivot B too compressed, with* FERR_COMP = “NON “**: in this case the reinforcement density is set to -1 for the element (and the calculation on the other facets of the” 2D “element is ignored)

if the “1D” element or at least one facet of the “2D” element is in pivot C too compressed with* FERR_COMP = “NON “**: in this case the reinforcement density is set to -1 for the element (and the calculation on the other facets of the” 2D “element is ignored)

if* FERR_SYME = “OUI “and the algorithm does not succeed in determining a symmetric reinforcement for the” 1D “element (or for at least one facet of the” 2D “element) that respects the tolerance threshold specified in the keyword SEUIL_SYME ****: in this case the reinforcement density is set to -1 for the element

if the*”1D”** element is subjected to deviated bending, and if the iterative dimensioning algorithm by checking the Bresler inequality fails to converge: in this case the reinforcement density is set to -1 for the element

if* TYPE_COMB = “ELS_QP “** and the iterative sizing algorithm based on the verification of the crack opening inequality fails to converge: in this case the reinforcement density is set to -1 for the element

5.3. Alarms issued during the calculation of transverse steels#

The ELU calculation of transverse steels can emit one or more alarms in the following cases:

  • if the concrete is too sheared: in this case the reinforcement density of the transverse steels is set to -1.
