3. Modeling A#

3.1. Characteristics of modeling#

Reinforced concrete walls and floors are modelled by DKT plate elements. Reinforced concrete is modelled with a simple elastic law. Beams and columns are modeled by POU_D_E elements. These are considered elastic. The sole is modelled by 3D elements and is considered elastic.

Damping is not considered in the modeling.

3.2. Characteristics of the mesh#

The mesh contains approximately 2,600 meshes and 2,700 knots (not including the sole). The mesh is that of the.

3.3. Tested sizes and results#

The first three natural frequencies are calculated from modal analysis. A simple non-regression test is done.
