Modeling:
1 element DKT (GEOB) superimposed on 1 element GRILLE_EXCENTRE (GEOA) supported on the same nodes.
Boundary conditions:
Nodes \(\mathrm{NO1}\) and \(\mathrm{NO4}\): \(\mathrm{DX}=0.,\mathrm{DZ}=0.,\mathrm{DRY}=0.\)
Nodes \(\mathrm{NO1}\) and \(\mathrm{NO2}\): \(\mathrm{DY}=0\)
Thermal load:
The concrete remains at \(20°C\).
Steel goes from \(20°C\) to \(120°C\) between the moments \(0\) and \(1\),
In both cases, the reference temperature is \(20°C\).
3.2. Characteristics of the mesh#
Knots: 4
Meshes: 1 QUAD4pour concrete and 1 QUAD4 for steel
