This study investigated seismic assessments of the Podestà Palace in Mantua (Italy). This masonry palace has a complex geometrical configuration that resulted from the addition of various units stratified over centuries. This feature makes seismic assessment challenging from a modelling perspective due to the interaction among units. Here, an...

The paper describes the derivation of fragility curves useful for the seismic risk analyses of existing unreinforced masonry buildings inserted in aggregate. The L-shaped examined aggregate consists of three adjacent structural units that may mutually interact during seismic events. The seismic assessment is focused on the corner unit. The...

Post-earthquake damage surveys systematically highlight the seismic vulnerability of monumental structures, calling for simple assessment procedures to address the design of effective retrofitting interventions. The structural complexity characterizing monumental structures, however, makes a reliable prediction of their seismic response a...

Equivalent frame (EF) methods are increasingly used to evaluate the global seismic response of historic masonry buildings. However, applying these methods to arched structures is challenging due to the lack of a standard EF strategy for masonry arches. This paper proposes a novel EF modelling solution for masonry arches in historic buildings...

This paper addresses the safety of connections within urban areas, where free-standing elements that menacingly overlook them are susceptible to potential overturning mechanisms. Such a condition recurs in post-earthquake scenarios and in historical centers abandoned after disasters in seismic-prone areas, which aimed to be restored to create...

The construction of reliable numerical models is a key aspect within the seismic assessment of existing unreinforced masonry buildings. However, it is also a complex process due to the many uncertainties involved that can affect the structural response. In situ tests allow for the acquisition of data at a local scale. Nonetheless, supplementary...

The paper presents the comparison of the results of non-linear static analyses performed with different software based on the equivalent frame (EF) modelling approach on a simple two-story unreinforced masonry building with rigid diaphragms. This study is part of a wider research activity carried out in the framework of the Italian Network of...
