Seismic risk assessment has become a crucial issue for optimal management of economic resources allocated to mitigation. For this purpose, in the last decades, several research activities were aimed update hazard, exposure, and vulnerability models that contribute seismic assessment. From perspective, present work focuses on developing new empirical damage fragility curves census-based typologi...

Within the context of structure deterioration studies, we propose a new numerical method based on use fragility curves. In particular, present work aims to theoretically study degradation concrete bridge structures subjected aggressive environments. A simple probabilistic curves is presented which allows forecasting lifetime considered structural system and best monitoring time. The was applied...

SSI and site amplification effects are investigated as influences on the seismic fragility of existing reinforced concrete moment-resisting frame dual frame-wall system buildings supported shallow foundations without interconnecting beams. We build upon a holistic methodology that accounts for soil–foundation–structure interaction using modular approach. calculate curves based nonlinear dynamic...

Abstract The seismic evaluation of masonry buildings in aggregate, largely diffused within the existing Italian and European building stock, represents a difficult open task that has not been exhaustively investigated so far. study proposes procedure aimed at evaluating potential impact combination local mechanisms site-amplification terms fragility curves on an unreinforced (URM) aggregate whi...

The effect of aftershocks on the fragility single-story masonry structures is investigated using probabilistic seismic demand analysis Finite element models an unreinforced (URM) structure and a confined (CM) are established their response characteristics when subjected to mainshock, aftershock, mainshock-aftershock sequence then comparatively investigated. effects use confining members studied...

In the context of historical seismology, studying behaviour historic masonry buildings is great importance, as they are witnesses past events. While interesting methods can be found in literature to assess seismic vulnerability structures subject strong earthquakes, topic moderate seismicity, encountered many European countries, still investigated. The present work proposes a global methodology...
