Perforated unreinforced masonry (URM) walls in out-of-plane (OOP) two-way bending are commonly encountered natural hazard investigations. However, related research is rather limited. This study focuses on the influence of openings capacity URM walls. An experimental database about perforated OOP was created. A brief review results show that arrangement opening area can significantly affect (def...

Performing a realistic assessment of unreinforced masonry structures involves designing and executing appropriate experimental tests on components for determining the material model parameters to be used in structural analysis. Considering recent developments which inverse analysis was as calibration framework, vertical flat-jack test is investigated this paper. Two simplified models are descri...

Unreinforced masonry structures are susceptible to man-made hazards such as impact and blast loading. However, the literature on this subject mainly focuses wall behavior, there is a knowledge gap about behavior of arches under high-strain In context, research aims investigate both quasistatic response dry-joint stone arch using discrete element method. Rigid blocks with noncohesive joint model...

The problem of structural stability of two medieval masonry towers is addressed. The geometrical and structural aspects of the towers were analysed and non-destructive tests were performed to assess the evolution of damage phenomena. The damage processes underway in some portions of the masonry were monitored using the Acoustic Emission (AE) technique. This method makes it possible to estimate ...

• Existing unreinforced masonry buildings show significant vulnerability to sequences of induced seismicity events. An intuitive seismic damage indexing scheme is proposed for URM structures. The considers both shear slipping and tensile cracking in masonry. A meso -scale model developed, the index equation applied identify evolution damage. could be applicable optical monitoring structural ins...

Abstract This paper aims at comparing the use of different software environments for study a simple unreinforced masonry building through nonlinear static analyses. The presented results are part wider research project conducted within ReLUIS consortium, and specifically task whose purpose is providing practitioners with tools an aware employment commercial packages modelling structures. In thi...

Abstract UnReinforced Masonry (URM) buildings constitute the majority of Italian building stock and represent one most vulnerable construction typologies, as emerged during seismic events occurred in last decades. The objective present work is proposal a methodology for vulnerability fragility assessment different typologies URM buildings. Through statistical analysis post-earthquake damage sur...
