“…Due to the flow lines associated with the shaping process, clay bricks from G4 have a similar compressive strength to bricks with a low sintering level, from G1 and G2, as shown in Figure 6b. Clay bricks from G3 have open porosities ranging between 12% and 20%, much lower than in similar studies [7,9], an estimated sintering temperature up to 1000 °C, and therefore an unusual compressive strength. …”

“…The mechanical analysis of bricks is common in many of them, including the works of Fernandes and Lourenço [6], Singha, et al [7], Matysek et al [8], Balasubramanian et al [9], Azeez et al [10], Pérez-Gálvez et al [11], Brozovsky et al [12] and Bajare et al [13]. Because of the difficulty of extracting samples, estimates of the bearing capacity of brick walls based on empirical formulas and analytical models that use the bricks and mortar strength are very useful.…”

Abstract:Interventions in historic brick buildings require an exhaustive analysis of the current characteristics of bricks in order to establish the role performed by these elements in the buildings. This study presents the results of an experimental analysis of the compressive strength of brick specimens extracted from different buildings built in the 19th and 20th centuries in the province of Zamora (Spain). The study analyses specimens with very different characteristics to compare results from different masonry units and manufacturing processes. Specimens are classified into four groups according to their macroscopic and microscopic analyses. Compressive strength results are correlated to the above classification and to the results of density, absorption and open porosity of the samples. The compressive strength results present high variation between clay bricks (9.2-64.4 N/mm 2 ) and between samples extracted from the same brick due to the heterogeneity of the material. Correlations between compressive strength and open porosity, absorption and dry density values are observed, with less dispersion in the case of high sintering level, up to 1000 • C. Finally, the compliance with the current Spanish Technical Building Code with respect to their compressive strength is checked.

“…This behavior is in contrast to the cast and press historic brick units that have lower strengths and a larger capacity of deformation in uniaxial strain, with a more evident and stable inelastic response. Furthermore, it was often observed that most of the burnt clay brick prisms fail due to the formation of vertical splitting cracks along their height [56]. Finally, the commonly assumed bilinear compressive stress-strain curves for burnt clay bricks masonry is also attributed to brick cracking and mortar nonlinearities.…”

Seismic events have repeatedly highlighted the vulnerability of existing masonry buildings. Seismic retrofitting is frequently focused on improving the connection between walls and roof for ensuring behavior able to resist loads from any horizontal direction. This paper deals with the design of masonry ring-beams made of clay bricks reinforced by natural fibers. Various solutions to ensure a masonry building box-behavior are possible, but this is a good combination of both static and conservation requirements, as it allows the use of bio-composites and grouts. It is a relevant possible alternative to the traditional reinforced concrete ring-beams, which are proven to be very ineffective under earthquakes. A simplified model for designing clay brick beams reinforced by flax fibers is provided, and a comparison with customary and traditional floor/roof masonry ring-beams is carried out.

“…In the light of the above a vast database has been composed that consists of 232 experimental data sets (Table 2) that have been obtained from 21 different experimental published works [10,12,48,52,[64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80]. During the experimental data selection from the literature it was taken under consideration the compressive strength of the masonry brick (f b ), the compressive strength of mortar (f m ), the height-to-thickness ratio of the masonry prism (h/t), the volume fraction of the masonry brick (VF b ) and the volume ratio of bed joint mortar (VR mH ).…”

The masonry is not only included among the oldest building materials, but it is also the most widely used material due to its simple construction and low cost compared to the other modern building materials. Nevertheless, there is not yet a robust quantitative method, available in the literature, which can reliably predict its strength, based on the geometrical and mechanical characteristics of its components. This limitation is due to the highly nonlinear relation between the compressive strength of masonry and the geometrical and mechanical properties of the components of the masonry. In this paper, the application of artificial neural networks for predicting the compressive strength of masonry has been investigated. Specifically, back-propagation neural network models have been used for predicting the compressive strength of masonry prism based on experimental data available in the literature. The comparison of the derived results with the experimental findings demonstrates the ability of artificial neural networks to approximate the compressive strength of masonry walls in a reliable and robust manner.
