This paper examines the support of an I-beam on a concrete wall. The model takes into account the unilateral contact between the beam and the concrete wall, which leads to a redistribution of interaction forces and, consequently, the maximum stresses that occur in the concrete in the contact area. Different scenarios with varying beam embedment depths into the wall are calculated. The distributions of interaction forces in the contact area between the wall and the beam under one-sided and two-sided interaction are presented. Based on the obtained results, it can be concluded that the maximum compressive stresses in the concrete in the contact area are reduced in the nonlinear formulation with a certain beam embedment depth.
