8. Force transmission
Load-bearing elements are subjected to vertical and horizontal forces due to the combination of various external stresses, and must be transmitted to stable points. The dimensioning of a structure starts with the upper parts, in the logical order: roof, framework, intermediate floors, walls, foundations.
The vertical loads to be taken into account are :
permanent loads consisting of the dead weight of all materials used in the structure, 20% of operating loads (estimated at 150 kg/m 2 for a dwelling);
temporary loads, comprising 80% of operating loads and climatic surcharges (snow and wind).
