Influence of the Horizontal-to-Vertical Compressive Strength of Hollow Clay Bricks on the In-Plane Drift Capacity of Unreinforced Masonry Walls

The seismic damage of masonry walls is reflected in cracks that tend to start at the head and bed joints and subsequently propagates through the masonry units. In this regard, the horizontal-to-vertical compressive strength ratio of bricks might have the a ...

Understanding building damage through the lens of the Swiss post-seismic reconnaissance mission of 2023 Al Haouz, Morocco, earthquake

Savvas Saloustros

A team of scientists and engineers from Swiss institutions participated in a post-seismic reconnaissance mission in Morocco following the magnitude 6.8 earthquake of September 8, 2023. We visited different heavily affected towns and villages, located from ...

Investigation of the bed joint reinforcement effect on the drift capacity of modern unreinforced masonry walls

Katrin Beyer, Savvas Saloustros

Bed joint reinforcement significantly affects the shear capacity of masonry walls due to its effective ability to transfer shear forces through a diagonal crack, but how does this phenomenon impact its drift capacity? This paper presents an experimental st ...

Experimental Investigation on Size-Effect of Rubble Stone Masonry Walls Under In-Plane Horizontal Loading: Overview and Preliminary Results

Katrin Beyer, Savvas Saloustros

Rubble stone masonry is a common construction typology of historical city centres and vernacular architecture. While past earthquakes have shown that it is one of the most vulnerable masonry construction typologies, there are few experimental campaigns giv ...

Experimental testing and structural analysis of composite tile – reinforced concrete domes

Savvas Saloustros

Conventional formworks for concrete curved shells either are expensive, complex and wasteful or have formal restrictions. Using tile vaults (also known as timbrel, Guastavino, thin-tile or Catalan vaults) as stay-in-place formwork for concrete shells could ...

Geometrical digital twins of the as-built microstructure of three-leaf stone masonry walls with laser scanning

Yves Weinand, Katrin Beyer, Julien Gamerro, Andrea Settimi, Savvas Saloustros, Andrea Cabriada Ascencio

Research on irregular stone masonry walls is hampered by the lack of detailed geometrical models of their internal micro-structure, i.e. the shape and size of each stone and its position within the wall. Without such a geometric digital twin of walls teste ...

Correlation between sonic pulse velocity and flat-jack tests for the estimation of the elastic properties of unreinforced brick masonry: Case studies from Croatia

Savvas Saloustros

Historic urban cores in southern Europe are characterized by a significant number of existing unreinforced masonry structures that are known for their seismic vulnerability. The first step in the preservation of such damaged buildings is condition assessme ...

Image-based geometric digital twinning for stone masonry elements

Katrin Beyer, Bryan German Pantoja Rosero, Savvas Saloustros

We present an image-based pipeline for generating geometrical digital twins (GDTs) of stone masonry elements with detail down to the stone level. For this purpose, we acquire RGB images of the individual stones and of the wall during the construction phase ...

Historical Development and Seismic Performance of Unreinforced Masonry Buildings with Vertical Extensions in the City Centre of Barcelona

Savvas Saloustros

This paper presents the historical development of the vertical extensions of unreinforced masonry buildings in the Eixample district of Barcelona and their impact on the seismic behaviour. Existing masonry buildings of Eixample present significant seismic ...

Modelling of in-plane seismic behaviour of one-way steel or timber jack arch floors in existing buildings

Savvas Saloustros

The type of floor system has a decisive role in the seismic performance of unreinforced masonry buildings. The in-plane stiffness of the floors has to be adequately represented in the numerical modelling of existing buildings, as it can influence their sei ...

Drift Capacity Models for the New Masonry Chapter of Eurocode 8 Part 1-2

Katrin Beyer, Savvas Saloustros

The masonry chapter of the new Eurocode 8 Part 1 contains several novelties, including new differentiation between unreinforced masonry typologies with regard to drift capacities and therefore q(D)-factors. Drift capacity models for masonry walls are empir ...

Experimental investigation of the in-plane seismic response ofrubble stone masonry walls

Katrin Beyer, Savvas Saloustros

A large experimental campaign on the in-plane seismic response of rubble stone masonry walls is currently under development at the Structural Engineering platform laboratory at EPFL (Switzerland). The main objective of this campaign is the experimental inv ...

Experimental setup and numerical evaluation of the compression test on thin tiles for masonry timbrel vaults

Savvas Saloustros

Compressive tests on clay tiles used in historical masonry timbrel vaults are hindered by the relatively small thickness of the specimens, resulting in buckling or confinement problems depending on the loading direction. This paper presents an experimental ...

Seismic vulnerability index method for hybrid timber-masonry structures. Numerical calibration and application to the city of Valparaiso, Chile

Savvas Saloustros

This paper presents a procedure for the extension of the Vulnerability Index Method (VIM) to the seismic assessment of hybrid timber-masonry buildings. The research is based on the execution of a detailed numerical study of this peculiar structural typolog ...
