This paper evaluates the seismic behaviour of a group of masonry buildings through the application of a simplified method. The method is based on the definition of a vulnerability index supported on few characteristics of the buildings and provides an estimation of the expected damage on the buildings as a function of the intensity of the...

This article presents the results of the numerical simulations of a dynamic experimental campaign on the shaking table. The specimen is a full-scale masonry cross vault without and with the textile-reinforced mortar used as a strengthening solution. The specimen was tested in the scope of the European project SERA.ta 07 "Seismic Response of...

The relevance of the safeguard of masonry cross vaults is evident in churches, palaces, and cloisters of most European countries. Nevertheless, their seismic behaviour is still an aspect to be deepened. In this regard, the purpose of this paper is to study the dynamic three-dimensional behaviour of a reduced scaled dry joint groin vault. The...

The seismic safety assessment of 3D complex structural elements of historic buildings, such as groin and rib vaults, is a challenge and experimental tests can provide relevant data for this purpose. This paper presents the results of two experimental campaigns about a reduced scale 3D printed vault characterized by asymmetric boundary...

The article proposes a procedure for the derivation of fragility functions for unreinforced masonry buildings considering the in-plane and out-of-plane response. Different approaches are considered for the generation of the corresponding fragility functions and for the evaluation of the propagation of uncertainties. The contributions for the...

This article describes the application of the procedure for the derivation of fragility functions presented in the companion article entitled Fragility functions for tall URM buildings around early 20th century in Lisbon. Part 1: methodology and application at building level. The procedure, based on the execution of non-linear analyses, was...

The article addresses the seismic vulnerability assessment of a typology of unreinforced masonry buildings constructed in Lisbon between the nineteenth and the twentieth centuries. The main architectural and structural features of these buildings are presented. This supported the identification of the main uncertainties affecting their seismic...

The Canterbury earthquake sequence, in 2010-2011, has highlighted once again the vulnerability ofmonumental structures, in particular churches, and the importance of reducing their risk from an economic, cultural and social point of view. Within this context, detailed analysis is reported of the earthquake-induced damage...

This paper presents a benchmark exercise for the seismic assessment of unreinforced masonry (URM) buildings as a follow-up of a blind prediction test organized in the context of the European Conference of Earthquake Engineering Series. The blind prediction exercise was aimed at better defining the open issues in current procedures for modeling...

Earthquakes cause severe damage to masonry structures due to inertial forces acting in the normal direction to the plane of the walls. The out-of-plane behavior of masonry walls is complex and depends on several parameters, such as material and geometric properties of walls, connections between structural elements, the characteristics of the...
