1. Presentation of the test case#

1.1. 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:

1.2. Meshing#

The mesh is as follows:

1.3. Material & Geometric Properties#

Concrete material is applied to the entire structure.

  • The Young \(E=30000\mathit{MPa}\) module

  • Poisson’s ratio \(\mathrm{\nu }=\mathrm{0,2}\)

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

1.4. Loading#

The load is:

  • The base is recessed.

  • The weight is applied to the entire structure,

  • Surface pressure \(F=-10\mathit{kN}/m\mathrm{²}\) 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.

1.5. 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: \(\mathit{DZ}=-\mathrm{0,0107}m\), Case Q \(\mathit{DZ}=-\mathrm{0,0153}m\)) corresponds to the displacement resulting from POST_COMBINAISON \(\mathit{DZ}=-\mathrm{0,026}m\).

This documentation is deliberately brief.
