Control and monitoring of buildings foundation : applications in very high buildings structure
Seixas, Andrea de, Jose Roberto de Seixas and Jose Jorge de Seixas
The analysis of the foundation behavior requires the study of the interaction between the concrete structure and the ground. The control and the monitoring of foundations can be restricted the measurement of settlements and displacements. Thus being, the confirmation of the quality of executed foundations already comes to still more stimulate the job of geodesic technologies in civil constructions, situations these, still rare in Brazil, thus breaching, of a form or another one unconsciously, the fear of the impact, on the part of the constructors, the installation of instruments of measurement in this area. Accidents come being, each time more, detected in urban environments, as it is the case of the Metropolitan Region of Recife (PE), where are well-known that the almost uncontrolled development of civil constructions are predominantly neglected, aggravated by the soil quality. The land on which they will fall again future projected loads, becomes element inquiry key, therefore exactly after the laboratory and field assays it remains the doubt how much to its behavior. For its diagnosis a perfect interaction is necessary enters the soil prospect company, the designer, the contractor and the consultants. Similar by that during the execution of the civil construction basic decisions for the perfect harmony can be taken between what was projected and the area of the construction, which will support the same. The necessity is then in following the execution of the workmanship after the accomplishment of the foundation and to investigate if its behavior is as foreseen theoretically inside of a permissible limit of deformation from the measurement of its settlements and displacement. For this the methods are excellent technician of Geodesy applied to engineering to subsidize the distributed point-object measurements in the study area.
