Design of precast panels for individual housing

Ductal/Termédia precast panels (LAFARGE)

Design studies for panels intended to individual housing construction. These panels are made of a shell of Ductal concrete mechanically connected to a Thermedia understructre. The study mainly focused on the design and the optimisation of the process taking into account the structural characteristics of the external Ductal shell as a bracing element under seismic and wind loads.

The precas panels are the supporting structure of the house, they lay on isolated base foundations. They are made of a 18 mm external Ducal shell, and a Thermedia understructure. These two elements are mechanically connected by steel rods, which ensure strain transmission in panel plans for which the Ductal shell has a seismic and wind bracing role.

Study details :
- Gravity loads (dead weight, permanent additional loads, exploitaion load), climatic loadings (wind, snow), and seismic sollicitation.
- Finite element modeling including the Ductal shell, the Themedia understructure and the mechanical connectors.
- Sensitivity study on the support conditions, the panel geometry, etc, in order to determine the process optimal conception.
- Implementation for the 8 panels of a house.
- Design of the panels, layout drawings, reinforcement drawing.
