Presentation of the test case
========================




Geometry
---------

The geometry, created under CIVIL_MASTER, is on 3 levels. It is composed of 6 sails, 3 floors, 4 columns and an opening located in a veil. It is illustrated by the following figure:

Material & Geometric Properties
-----------------------------------

Concrete material is applied to the entire structure.


* The Young :math:`E=30000\mathit{MPa}` module


* Poisson's ratio :math:`\mathrm{\nu }=\mathrm{0,2}`

The thicknesses of the walls and floors are :math:`200\mathit{mm}` and the beams have a square section with a :math:`200\mathit{mm}` side.




Loading
----------

The load is:


* The base is recessed.


* The weight is applied to the entire structure,


* Surface pressure :math:`F=-10\mathit{kN}/m\mathrm{²}` is applied to the roof of the structure and to a lower web (Fig 1).

Two load cases are defined and correspond respectively to Weight (Case G) and Pressure (Case Q). Then, POST_COMBINAISON is used to sum the loads.




Validation
----------

The displacement in a node of the intermediate floor is extracted following the calculations of the load cases and then of POST_COMBINAISON by ensuring that the sum of the displacements of the load cases (Case G: :math:`\mathit{DZ}=-\mathrm{0,0107}m`, Case Q :math:`\mathit{DZ}=-\mathrm{0,0153}m`) corresponds to the displacement resulting from POST_COMBINAISON :math:`\mathit{DZ}=-\mathrm{0,026}m`.

This documentation is deliberately brief.
