FOUNDATION DEFINITION: Foundation is the structural element that has for function to transmit the load of the structure to the ground without provoking rupture of the land of foundation or the proper linking element and whose you stress can satisfactorily be absorbed by the structural set. The system of foundations is formed by the structural element of the building that is below of the ground (being able to be constituted by block, prop or tubulo, for example) and the bulk of involving block under the base and throughout the shaft. FUNCTION OF the FOUNDATIONS To support with security loads proceeding from the building, that is, is the structural element that transmits the one load construction for a more resistant layer of the ground. Thus, the foundations must have adjusted resistance to support the tensions caused for the solicitant efforts. Moreover, the ground needs resistance and rigidity appropriate not to suffer rupture and not to present exaggerated or distinguishing deformations.
CONSTRUCTION LOADS the loads of the construction are gotten by means of the plants of architecture and structure, where the proper weights of the constituent elements and the overload or useful load are considered to be considered in the flagstone that is normalized in function of its purpose. Eventually, in function of the height of the construction the action of the wind will have also to be considered on the construction. Table 1 more supplies the specific weight of the used materials in the constituent elements of a construction, while the table the 2 useful overloads or loads in lining or floor flagstone in accordance with its purpose DEEP FOUNDATIONS DEFINITION: They are those where the load is transmitted to the land through its base (tip resistance) and/or lateral surface (attrition resistance). The deep foundations are seated to a bigger depth that two times its lesser dimension in plant. The deep foundation, which possesss great length in relation its base, presents little capacity of support for the base, however great load capacity due to the lateral attrition of the body of the element of foundation with the ground.
