Abstract :
[en] The paper focuses on the interpretation and numerical simulation of the results of shaking table tests on two masonry buildings mock-ups, performed at Laboratório Nacional de Engenharia Civil (LNEC) in Lisbon, within the purposes of the SERIES project Transnational Access activities (Mendes et al. 2014, Lu et al. 2014). Shaking table tests have produced a huge amount of remarkable data that need to be properly interpreted, in order to get general and synthetic information on the seismic behaviour. To this aim, different techniques of data interpretation are applied, consisting in some traditional approaches (e.g. the frequencies analysis or the identification of an equivalent linear system) and in the innovative use of the Proper Orthogonal Decomposition (POD) technique. Together with the interpretation of experimental results, the paper also illustrates the nonlinear dynamic simulation of these two models by Tremuri program (Lagomarsino et al. 2013), which is based on the equivalent frame approach. The results achieved showed a good agreement between experimental and numerical results, highlighting that the tools adopted are quite effective in interpreting the nonlinear response of URM masonry structures.
