Abstract
Although damage levels consistent with the EMS-98 scale represent a concept that is well established and intuitive in engineering practice, ensuring a coherent correspondence across the different approaches used to derive fragility curves (i.e., empirical, mechanical-analytical, and mechanical-numerical) is far from straightforward. This is due to the variety of variables that may be adopted (e.g., damage data from post-earthquake survey forms, interstorey- drift, roof drift, damage variables from constitutive laws, etc.) as well as the different conversion criteria employed. Such variability can lead to significant impacts on the results. In the seminar, this issue is addressed, with particular insights provided from the use of nonlinear dynamic analyses (NLDA) for masonry structures. Specifically, a multi-scale approach is proposed to fully exploit the large amount of data generated by NLDA. The method is inherently self-consistent and do not require the support of nonlinear static analyses for interpretation, as is commonly done in the literature.
Short bio
Serena Cattari is Full Professor of Structural Engineering at the Department of Civil, Chemical and Environmental Engineering. Her main research area deal with Earthquake Engineering, Masonry Structures and Risk studies. SC is the Coordinator of the PhD Program in Security, Risk and Vulnerability and to date supervised 18 PhD Students. SC is Associate Editor of Earthquake Spectra. She is co-author of more than 230 scientific contributions, of which 96 papers on international journals indexed in SCOPUS. She served as local responsible of the research unit of UniGe in several national projects funded by MUR (e.g. PRIN 2017 DETECT-AGING - "Degradation Effects on sTructural safEty of Cultural heriTAGe constructions through simulation and health monitoring"; PNRR RAISE) and ReLUIS-DPC programs (e.g. WP4 MARS - "Seismic Risk Maps and damage scenario"; WP10 - "URM nonlinear modelling - Benchmark Project").
Sandwiches are offered at the end of the seminar.
