RESUMO

To understand strain and monitoring methods is essential in the prevention of accidents and in the maintenance of works of civil engineering. GPS has been increasingly becoming a powerful technology in the control of strains of structures. The aim of this research is to determine parameters for analysis of the behavior of a structure, by using simulation model and GPS. A review of systems and stages involved in the monitoring strain are revised and presented. With the scientific program GIPSY is obtained the repeatability and time series of the points located in a building. The behavior of the decks of a viaduct is analyzed with base in the data GPS. Determination of displacements and of strain parameters becomes possible with simulations. A plate is used to simulate these parameters and the mathematical model relates them with observations. Dilation or the principal strains are determined. In order to verify stability, it is carried out a global congruent test.
