Considerations on the Use of Geodetic and Satellite Methods in the Study and Monitoring of Building Behaviour

Two groups of methods are being used during the complex process of studying the behavior of the buildings: physical and geometrical methods. Within the first group of methods, the setting up of the instruments is made directly inside of the studied building moving thus together with the latter and revealing this the relative values of the deformations. The second group containes the geodetic and photogrammetric methods by whose mean we are determinating the position of some fixed points of the buildings, with reference to the immobile points which are positioned around the building, being this able to obtain the absolute values of the de formations and displacements of the considered building. The use of the geodetic and photogrammetric methods do not exclude the use of the physical methods, more than they are strongly related and completing one another. Within this paper are made some considerations concening the use of the geodetic methods for studying the behaviour of the buildings, presenting the fact that these methods are representing a fundamental system within the experimental and in situ studying process, and that these methods cannot be replaced. Due to the high precision of the measurements and estimating of the accuracy of the results, the geodetic methods ensure the obtaining of the most realiable values of the parameters characterising the state of stress and deformations of the buildings.
