Tartalmi leírás:
Compared to commonly applied methods, a better estimation of probable intensities of historical seismic events can be achieved by probabilistic seismic analysis of structures damage due to seismic events. The method usually requires analysing historical data on the damage of several structures and their behaviour, in order to evaluate and identify critical points and probable collapse modes that could lead to the described damage. As a case study, preliminary analysis of the Zsámbék late Romanesque church, in Hungary, which collapsed due to Komárom earthquake in 1763 is discussed in this paper. A 3D finite element linear elastic and a nonlinear macro-model have been built from the descriptions and expected behaviour of the structure, and validated through a sensitivity analysis. The critical points have been identified through modal response spectra and pushover analysis (fol-lowing EC8-1) and comparing the results with the described damage and other research works on this topic. Using the main stresses, strains and displacements and following a step-by-step collapse simulation the probable collapse mode has been evaluated. The numerical modelling was developed in the FEM code AxisVM. The results support the development of non-linear FEM and DEM numerical models, relying on modal pushover or time-history analysis, and characterizing the global and the specific behavior of some of its structural elements, thus allowing for a better account for future estimations of the intensity of Komárom earthquake.
