In the last decades, the Synthetic Aperture Radar (SAR) technology has undergone a quality increase in signal acquisition and therefore a greater quality and precision of the measurements.

Abstract

In the last decades, the Synthetic Aperture Radar (SAR) technology has undergone a quality increase in signal acquisition and therefore a greater quality and precision of the measurements. This allowed to develop a technique capable of capturing the displacements over time, called Differential Interferometric SAR (D-InSAR). At first, the Satellite Interferometry (InSAR) technique was used to determine the displacements that occurred as a result of earthquakes, land-slides and volcanic eruptions. Now, thanks to the sensitivity achieved, several studies are currently ongoing to investigate the possibility of using these techniques to monitor the movements and deformations of buildings and infrastructures. In this paper, an attempt is made to evaluate the correlation between DInSAR data and the damage states of buildings based on differential settlement scenarios. For this purpose, nonlinear numerical models of RC buildings have been developed and analyzed.
