The analysis model used is composed of a thick triangular finite element mesh, which considers shear deformation. They are made up of six nodes, at the vertices and side mid-points, each with six degrees of freedom.
The wing walls are designed as a bar fixed to the footing subject to earth pressures. They are optionally divided into spans, varying in height and dimensions of the footing.
The stress diagram, displacement stress diagram and the deformed shape drawing for any loadcase can be consulted in the 3D view.
