v7.23.102 HSNS102 - Reinforced concrete plate with thermal loading

Summary:

The main purpose of this test is to verify the modeling of reinforced concrete elements under thermal loading using three techniques:

• Modeling A: Shell model: DKT + GRILLE_EXCENTREE

• B modeling: Solid model: Volumic + GRILLE_MEMBRANE

• C modeling: Solid model: Volumic + MEMBRANE

The objective is to verify the mechanical response by comparison with a reference solution obtained analytically.

In addition, it tests, in B modeling, the MATRICE = ELASTIQUE functionality of STAT_NON_LINE for the elements GRILLE_MEMBRANE, as well as the options EPVC_ELGA, EPME_ELGA, and EPSP_ELGA.

In C modeling, we also test the calculation of options EFGE_ELGA and EFGE_ELNO on the elements of MEMBRANE (linear and non-linear).
