Modeling A
==============

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.


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.

Tested sizes and results
------------------------------

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