v6.04.401 SSNV401 — Verification of the law of behavior BETON_RAG: creep phenomenon

Summary:

These tests validate the BETON_RAG law of behavior on a cube stressed in compression with the maintenance of either a stress or a deformation. The response of the model is compared to solutions obtained by analytically solving the equations that govern the behavior [R7.01.26].

Four models are proposed:

• Modeling A: compression creep test with a stress imposed on a cube that is free to deform in the direction perpendicular to the load.

• Modeling B: compression creep test with a deformation imposed on a cube that is free to deform in the direction perpendicular to the load.

• C modeling: Compressive creep test with a stress imposed on a confined cube (blocked transverse deformations).

• Modeling D: compression creep test with a deformation imposed on a confined cube (blocked transverse deformations).
