“…The adhesion between the blocks is achieved using traditional mortar based on earth or lime; it also allows filling the void, to seal and to limit the punching. Due to its tensile stress and seismic vulnerability (Abrams, 2001;Lagomarsino, 2006;Pereira, 2021), more studies and reinforcements are required before it can be used in high seismicity areas. Historically, masonry buildings have been built in such a way that the masonry works in compression (bearing walls, arches and vaults).…”

Reinforced concrete is currently the most used material in construction, posing a significant environmental concern as GHG emissions and problems related to durability and recycling. Therefore, governments have started to encourage the usage of traditional buildings which offer interesting advantages. However, due to poor mechanical and technical performance, as well as a lack of regulations and know-how their usage is limited. The research work carried out on eco-materials has improved their mechanical performance as well as their water resistance. Despite the importance of this study, it is clear that the proposed ecological models cannot yet compete with modern constructions in terms of mechanical performance, rate of construction and economic efficiency. To combine the advantages of these two construction methods: the modern one with its better mechanical performance and economic efficiency, and the traditional one with its insulating power, ecological and bioclimatic aspects, it is proposed to investigate the aspects of the concept "hybrid building technology" which is less polluting, competitive and capable of reducing the impact of the construction on the environment. This article's goal is to define the concept of hybrid construction technology via an analysis of two modern construction trends: sustainable construction techniques and reinforced concrete buildings. Furthermore, the article discusses several hybridization techniques in the building sector and offers some examples of hybrid construction technology models. Future prospects and recommendations for developing a hybrid building research field are also provided. As a conclusion, this third way in construction will allow for good outcomes in the reconciliation of construction, economics, and man with the environment.

“…A Total Strain Rotating Crack (TSRC) material model that is available in DIANA (Manie and Kikstra, 2016) was used to model the non-linear behaviour of the masonry, and it is usually adequate for this purpose (Pereira et al, 2020;Aşıkoğlu et al, 2020;Ciocci et al, 2018). This material model describes the stress as a function of the strain and follows a smeared approach for the fracture energy.…”

This work aims to numerically simulate experimental pull-out tests in masonry wall anchors. Advanced Finite Element (FE) 3D models were built to fully reproduce the loadbearing capacity, the failure mode, the stresses and the force-displacement curve and, in general, all the phenomena involved for both brick and stone specimens. Three different modelling approaches were considered. First, a macro-model was adopted, where both brick and stone masonry were assumed as a homogeneous isotropic material.The steel bar and the grouted mortar of the anchor system were considered linear elastic and the system was placed in the specimen using interfaces. The second approach was a unit model, developed with the aim to reproduce the influence of the unit where the anchoring fastening is located. The last approach studied was a micro-model, where both the units and the mortar are considered. The challenge in modelling these systems is highlighted from the different modelling strategies used and compared.

“…In most of the Italian Regions it was seen that the seismic activity was intense through the centuries and especially in the area that defines the Apennine region between Umbria and Marche where the heritage is characterized by rural, vernacular masonry [5]. The material mostly used to define the construction techniques of the area is called "Scaglia Rossa" and is the focus of the experimental campaign and numerical non-linear modelling approach of the present paper [6], [7]. In Section 2, the methodology for the experimental campaign is presented and it is explained also the numerical approach used to identify the results of the campaign numerically.…”

This paper outlines the characterization of masonry walls composed of "Scaglia Rossa", a typical stone of the Apennine area between the Umbria and Marche Regions in Central Italy. The study focuses the assessment of the mechanical behavior by means of an experimental campaign carried out in the laboratory of the Polytechnic University of Marche, where the samples of "Scaglia Rossa" masonry, obtained from the controlled demolition of three school buildings, were reconstructed with the same techniques of the 1950s-'60s, and then tested in order to identify both the constituent materials, stone and mortar, and the composite masonry. The experimental tests were prior to a numerical analysis implemented by the adoption of a nonlinear model capturing the cracking behavior. The main mechanical parameters were then calibrated by means of an optimization algorithm of Levenberg-Marquardt, considering a continuous approach in macro-modelling techniques and obtaining resistance parameters not deriving directly from the experimental tests. The comparison between the results obtained from the Levenberg -Marquardt algorithm by changing the parameters of the damage model based on data given by the experimental campaign allowed to confirm the validity of the approach used.
