v3.05.103 SSLX103 — Flexion of a 3D reinforced concrete beam with reinforcements modelled by bars

Summary:

The objective of this test is to validate the modeling of steels by linear SEG2 bar elements in concrete modeled by quadratic solid elements.

Two models are compared:

• a quadratic solid element contains a linear bar element

• a quadratic volume element contains two linear bar elements

to a reference calculation where the bar elements are quadratic obtained with Castem.
