Support displacements are a major cause of damage to masonry arches. In the last decades, the effect of large support displacements on the stability of masonry arches has been widely investigated. However, there is still a lack of studies dealing with inclined support displacements. In this work, a large experimental campaign was performed on a...

Cultural heritage buildings as they appear today are the result of continuous transformations occurred over the centuries. For this reason, their structural assessment should integrate structural analysis with a deep knowledge of the building history, actual geometry, damage, past alterations, and actions undergone over time. This paper...

In this paper, the structural response of a segmental dry-joint masonry arch subjected to increasing support displacements was investigated. The arch behaviour was analysed in the framework of large displacements using finite element (FE) and rigid block (RB) models, both based on a micro-modelling strategy. Once the two modelling approaches...

This paper presents a first contribution to the damage assessment of historic masonry churches exposed to slow-moving landslides. No studies have ever been devoted to systematically investigating the effects of slow-moving landslides on this type of structures. In this work, a damage survey campaign was performed on 33 listed churches located...

This paper aims to investigate the response of a scaled segmental dry-joint masonry arch to the settlement of one support. An experimental test and numerical simulations were performed by applying incremental vertical displacements at the right support up to collapse. The experimental test was carried out on a 1:10 small-scale model of the arch...

This article deals with the topic of seismic vulnerability of single-storey industrial buildings, proposing the design of a new system able to support the movement of the load-bearing structure during earthquakes. The targets of this solution at greater resilience, designed with prefabricated elements and innovative structure-cladding...

Churches struck by the earthquake sequence of 2016–2017 in Central Italy confirmed their seismic vulnerability, significantly higher than the one of other unreinforced masonry structures. This resulted in a much wider area affected by significant damages to churches, which were characterised by a rich variability of materials, typologies,...

Masonry vaults represent one of the most widespread types of horizontal structural elements in historical constructions. Vaults can be built according to different brick pat terns, which, in historical building practices, were generally chosen for technical reasons. Brick pattern is expected to play an important role in the global behaviour of...

Compared to simple masonry walls, numerical modelling of masonry vaulted structures is particularly complex due to their three-dimensional curved geometry and articulated masonry pattern. Moreover, the scarce availability of experimental data makes it difficult to validate numerical models for these types of structures. Recently, the simplified...

In this paper, the structural performance of masonry cross vaults is investigated with regard to the most common differential settlements occurring in historical constructions. Numerical parametric models are developed for vaults with different brick patterns and lateral constraints, in the presence/absence of infill. In particular, radial,...

Cross masonry vaults are common structural elements in historical buildings. They are largely diffused in all European countries, including those characterized by higher levels of seismicity. Although they have been constructed for centuries, they represent some of the most vulnerable elements of traditional architecture, especially with...

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...
