“…Due to its long historical prevalence, masonry consisting of clay bricks and lime mortar is abundant all over the world. Still today, a significant part of the building stock includes structural masonry members such as load-bearing walls [2][3][4][5][6][7][8]. Due to changes in regulations and uses, masonry buildings are often in need of structural re-evaluation and, eventually, of possible retrofitting interventions.…”

This research presents an experimental programme on the mechanical characterization of masonry under monotonic and cyclic uniaxial compression. Two different types of standard specimens, running bond walls and stack bond prisms, were built using handmade clay bricks and hydraulic lime mortar. The experimental results are compared and discussed in terms of strength, stiffness and deformability. It was observed that the two specimen types provided very similar results on both strength and stiffness. Cyclic loading tests carried out on a set of samples provided new experimental evidence on the stiffness degradation, loss of load carrying capacity for increasing irreversible compressive strains and energy dissipation. The paper presents eventually a thorough discussion about the comparison between the obtained experimental results with available predictive models for strength, stiffness and fracture energy of masonry under monotonic and cyclic compression loading.

“…The material degradation is mostly visible on the disintegration of the mortar and the desegregation and spalling of the bricks. This process is accelerated by the porosity of the materials and the presence of salts, either in the air, due to the proximity to the sea, for instance, or in the mortar itself and that migrates to the material's surface causing efflorescence and progressive degradation [9].…”

Masonry chimneys were key elements of post-industrial factory buildings. Built on a large scale in Portugal from the nineteenth century, factory buildings have been in use until the beginning of the twentieth century, afterwards being progressively abandoned, transformed or demolished. During this degradation process, the industrial chimneys are often separated from other structures and become isolated elements, i.e. sculptures to the memory of the site's past activity. Moreover, although most of these industries and chimneys were located outside ordinary living areas, they are actually surrounded by dwellings or placed inside leisure areas. This new framework demands safety evaluations of the chimneys, which involve preliminary on-site surveys. This work shows the analysis of the geometric and material data from on-site surveys and dynamic identification procedures carried out on 10 industrial brick masonry chimneys. In particular, it establishes correlations between the chimneys geometrical and mechanical characteristics and proposes simple procedures to help designers to assess the safety conditions of these chimneys and evaluate eventual reinforcement needs. This article is part of the theme issue ‘Environmental loading of heritage structures’.

“…Masonry towers are very peculiar structural typologies, and they are typically conceived to withstand only vertical loads, as it occurs for all historical masonry constructions [7][8][9][10][11][12][13][14][15][16]. Therefore, their seismic vulnerability is expected to be high and particular attention should be paid to their seismic assessment toward a preservation approach.…”

Seismic assessment is a paramount issue and a valuable instrument towards the conservation of vulnerable structures in seismic prone regions. The past seismic events have highlighted the vulnerability of masonry towers that is exhibited by severe structural and nonstructural damages or even collapses. The preservation of existing structures, mainly focused on the built heritage, is emerging and imposing substantial enhancements of numerical methods, including pushover analysis approaches. The accuracy of the estimated seismic capacity for these structures is correlated with the assumed strategies and approximations made during the numerical modeling. The present paper concerns those aspects by exploring the limitations and possibilities of conceiving pushover analysis in the finite element method environment. The most crucial target is tracing in a pushover capacity curve the corresponding initiation of structural damages, maximum load-bearing capacity, and the ultimate displacement capacity. Different recommendations for achieving this target have been proposed and illustrated for practical utilization. Three representative geometrical towers, adopting three different materials and five different load patterns, are investigated in this study. The load pattern’s role and necessity of the displacement-like control approach for the pushover analysis are exploited. This paper highlights the load-bearing capacity overestimation when the force-controlled are implemented. The material model influences the achievement of softening branch with a distinguishable displacement capacity.
