5. Keyword factor BETON_GLRC

This keyword factor is used to define the concrete material that will be supplied to the BETON/MATER keyword of DEFI_GLRC/RELATION =” GLRC_DM “.

5.1. Operand CODIFICATION

This operand works in the same way as the MAZARS keyword.

♦ CODIFICATION= “EC2”|”TEST”

• “EC2”: indicates that the parameters used in the definition of materials come from codification EUROCODE 2.

• “ESSAI “:indicates that the parameters used in the definition of materials come from test.

5.1.1. Case where CODIFICATION =” EC2 “

♦ unite_ CONTRAINTE

Unit of constraint for the problem \(\mathit{MPa}\) or \(\mathit{Pa}\): Mega-Pascal or Pascal. Entering this operand is mandatory, as it is necessary to return the material parameters to the unit system used to do the study.

♦ CLASSE

The compressive strength of concrete is designated by strength classes related to the characteristic strength measured on a cylinder or on a cube, in accordance with EN206 -1.

The classes available in the operator are all those defined in EUROCODE2:

“C12/15 » C16/20 » C20/25 » C20/25 » C25/30 » C30/37 » C35/45 » C40/50”

“C45/55 » C50/60 » C55/67 » C55/67 » C60/75 » C60/75 » C70/85 » C80/95 » C90/105”

5.1.2. Case where CODIFICATION =” ESSAI “

In this case, the user must fill in the following parameters which will be formatted in a « material » concept in order to be in the format expected by DEFI_GLRC. The user must provide these characteristics in a system of units compatible with his study.

♦ FCJ: Peak stress during compression.

♦ EIJ: Young’s module.

♦ EPSI_C: Peak deformation under compression.

♦ FTJ: Peak stress during traction.

◊ NU: Poisson’s ratio. (0.2 by default)
