Finite element analysis of Vittoriano building based on InSAR data

This paper discusses a novel methodology for evaluating buildings performance through advanced Finite Element Analysis (FEA) based on the data given by Interferometric Synthetic Aperture Radar (InSAR). A cracked wall of Vittoriano building, Rome, Italy is chosen as the case study. A detailed 3Dnumerical model of the wall was developed in ABAQUS. Concrete Damage Plasticity (CDP) modelwas utilized for defining the masonry material basedon the macro-modeling approach. The ground deformation acquired by InSAR is applied to thewall’s base. The crack propagation and stress concentration of the numerical model was in line with the real cracks observed on the wall. The results highlighted the high reliability of the InSAR data which could be used in structural behavior assessment.
