v6.02.119 SSNL119 - Static response of a reinforced concrete beam (rectangular section) with non-linear behavior

Summary:

The problem consists in analyzing the response of a reinforced concrete beam in 3-point bending to ruin through multi-fiber beam modeling [R3.08.08] or plate modeling using a homogenized reinforced concrete law. This test corresponds to a static analysis of a beam with non-linear behavior. The test models are:

• modeling A: concrete is modeled with Mazars’s damagable softening behavior law in its version \(\mathrm{1D}\) [R7.01.08] and steel is elasto-plastic, the type of elements used is POU_D_EM;

• modeling B: the reinforced concrete beam is modeled with the homogenized law GLRC_DM and a steel grid according to an elasto-plastic law representing lower steels;

• modeling C: the reinforced concrete beam is modeled with the homogenized law GLRC_DM with an averaged reinforcement cross section;

• D modeling: the reinforced concrete beam is modeled with the homogenized law DHRC.

• Modeling E: copy of modeling A with elements POU_D_TGM used to validate options EPSI_ELGA and EPSP_ELGA for this type of element.
