This paper presents a benchmark exercise for the seismic assessment of unreinforced masonry (URM) buildings as follow-up blind prediction test organized in context European Conference Earthquake Engineering Series. The was aimed at better defining open issues current procedures modeling and performing analysis URM buildings, by highlighting uncertainty that can influence results. work an overvi...

In this study, a system of discontinuous rigid blocks is employed to simulate the possible damage mechanisms in unreinforced masonry (URM) façades and load-bearing frame systems subjected settlement using discrete element method (DEM). First, modeling strategy validated utilizing available experimental results presented literature. Once there good agreement between computational models findings...

The growing concern for the preservation of old buildings and wide use masonry in construction civil works has led to a great development specific techniques strengthen structures. FRCM (fabric reinforced cementitious matrix) vegetal fibres arises as strengthening option be considered because low cost, density, recyclability biodegradability brought by fibres. In this study, numerical models we...

Abstract Unreinforced masonry buildings undergoing seismic actions often exhibit local failure mechanisms which represent a serious life-safety hazard, as recent strong earthquakes have shown. Compared to new buildings, older unreinforced are more vulnerable, not only because they been designed without or with limited loading requirements, but also horizontal structures and connections amid the...

This research performs a parametric study based on Equivalent Single Degree of Freedom (ESDOF) models for simplified seismic analysis unreinforced masonry (URM) structures. is necessary action due to the fact that it not affordable model and analyze populations buildings by using detailed continuum-based during regional damage loss estimation studies. Hence, this focuses sensitivity major struc...
