The role of model calibration in seismic FE analysis : the case study of an old reinforced concrete structure by using ambient noise modal analysis

In order to perform a reliable non-linear dynamic seismic analysis of a building, the first step is to build the linear numerical model of the structure and validate it by means of the modal analysis against in-situ measurements. The seismic analysis of the Perret Tower offers the opportunity to show the potentialities and the difficulties that can be faced in this preliminary though fundamental phase of the analysis. Without to enter in the details of the FE modeling, the attention is focused on the usual practice of “calibration” of the numerical models by means of in-situ modal analysis measurements and on the importance to understand which components of the structure have structural relevance.
