“…To compare the results of the static tests carried out by Rossi et al (2016) with the shake table tests (ST), the analysis of collapse mechanism was adopted, in which a sequence of photos, with the number and locations of the hinges, was used. Looking at Figure 10, the centre of the vault is the rst to collapse in both tests, due to its geometrical con guration and the verticality of the joints.…”

“…In order to simulate the particular boundary conditions that cause an in-plane shear response of the vault, the special testing device adopted by Rossi et al (2016) was used. It consists of a frame composed of four steel squared plates, linked to each other by the use of aluminium bar couples hinged at both ends with uniball joints.…”

The seismic safety assessment of 3D complex structural elements of historic buildings, such as cross vaults, is a challenge and experimental tests can provide relevant data for this purpose. This paper presents the results of two experimental campaigns in a reduced scale 3D printed vault characterized by asymmetric boundary conditions. The specimen adopted the typical geometry of groin vault (without ribs) and was made of polymeric bricks placed in an orthogonal bond disposition. The seismic behaviour of the vault was studied through quasi-static and dynamic tests using the shake table. In particular, an incremental dynamic analysis up to the collapse of the vault was carried out. The results obtained experimentally were analysed in terms of damage, collapse mechanisms, displacements, in-plane distortion and response spectrum-based analysis.

“…Furthermode, the use of Discrete Element methods is proving its efficacy because of their capacity to model the discrete nature of masonry and the possibility of considering large displacements [14][15][16]. Few researchers analysed the seismic behavior of vaults by simulating seismic actions as differential displacements applied to supports using both numerical [17] and experimental approaches [18][19][20].…”

Masonry vaults represent a pleasant typology of structural horizontal element in traditional architecture and historical buildings, widespread on a large scale along all the European countries, even those characterized by a high level of seismicity. However, they are some of the most vulnerable structural elements particularly under dynamic actions. Therefore, the assessment of their structural safety and the determination of their stress field is a very important task for preservation of historic buildings. Vaults have been studied from an architectural and structural point of view as sequences of arches, and thus extending the use of bidimensional tools of analysis. This assumption can be reliable for the analysis of barrel vaults, but it is not always the most appropriate solution for investigating more complex vaulted systems with a not negligible three-dimensional behavior. The paper presents on the analysis of a particular groin vault, typically found in monumental buildings which will be successively tested during an experimental dynamic campaign on the shake table. Among all the failure mechanisms of this type of vault, the shear failure is one of the most frequently recorded during post-earthquake surveys. The activation of the shear response is caused by asymmetric boundary conditions and difference in stiffness between two sides of the vault, as it occurs in groin vaults covering churches aisles characterized by the presence of a perimeter wall on one side and two columns on the other side. The main aim of the paper is to investigate the seismic response of a brick groin vault simulating the boundary conditions and loadings of an aisle in a three naves church prototype. Static and dynamic nonlinear numerical analyses were performed using a finite element model. The boundary conditions simulate from one side the presence of a perimeter wall and from the other side the two columns between the main and the lateral nave. The role of the infill and of the amplification of the seismic input are investigated. The results are analyzed in terms of ultimate displacement capacity, crack pattern and damage mechanisms.

“…In order to shed light on these aspects, this paper presents the results of a parametric analysis aimed at evaluating the influence of geometry, tensile strength and infill on the seismic behaviour of groin vaults. In particular, the ranges of vault dimensions (span, rise, thickness) were deduced from literature, from both historical [17] and experimental points of view [18][19][20]. The analyses basically focused on seismic capacity and failure mechanisms according to two different boundary conditions.…”

Considering the relevance and the artistic value of cross vaults in European seismic prone areas, a parametric study on the seismic capacity of this element is presented. In particular, the behaviour of the so-called groin vault is discussed, i.e. intersection at a right angle of two semi-circular barrel vaults. The influence of span, rise, thickness, infill, and masonry tensile strength is investigated with respect to two boundary conditions, representative of typical vault configurations within heritage buildings. The analyses were performed using an upper bound approach of standard limit analysis. For the sake of clarity, the adopted code framework is briefly reviewed. With the aim of identifying the most frequent failure mechanisms, the outcomes of the parametric analysis have been visually inspected and sorted according to the input parameters. Aiming towards a simplified assessment criterion, the resulting list of parameters was subsequently processed through multiple linear regression analyses that can help practitioners in quick seismic evaluation.
