“…Two approaches of micro modelling are applicable -simplified and detailed (Lourenço 1996). The conducted research (Lourenço 1996;Pina-Henrignes 2005;Haach 2009;Medeiros et al 2013) shows that both methods produce reliable results. Micro modelling is often used when new masonry unit solutions are analysed (Jaafar et al 2006;Thanoon et al 2008;Porto et al 2010;Del Coz Díaz et al 2007;Ghiassi et al 2013).…”

Highly hollow masonry units, which allow reducing the weight of masonry constructions and improving heat and sound insulation qualities, are commonly used in masonry construction. Filling the hollows with concrete, or concrete with light additives, results in complex masonry. Overall performance of such masonry is affected by initial stresses, which are caused by shrinkage deformations of different infill concrete and masonry units. Behaviour of infill concrete and concrete blocks is analysed by applying numerical detailed micro modelling. Experiments revealed that masonry deformations of blocks with concrete filled hollows are similar to those of longitudinal deformations of infill concrete samples. s-e relations were received through numerical micro modelling and compressive strength of masonry match values were estimated during experiments.

“…Recent earthquakes have shown that unreinforced masonry buildings do not behave adequately in case of seismic loading for the low tensile strength of masonry, by exhibiting brittle response and damage [5,6]. The experience made on several countries, characterized by a nonengineered construction technologies, has proven that the introduction of confining concrete elements can improve significantly the seismic performance of masonry structures, leading to higher lateral resistance and ductility.…”

This paper presents the experimental results of shaking table tests on two prototypes, made of unreinforced and confined masonry material, carried out at the laboratory of ENEA, Casaccia, Rome. The mock-ups have the same small-scale geometry, characterized by a rectangular plan of about 3.00 × 3.50 m in dimensions and a total height of about 4.00 m. The building models have two levels, in which three facades have openings not centered on both levels, while the fourth one results as a plane masonry wall. The two rigid floors are made of concrete/brickworks and steel for the first and second level, respectively. For both models, the dynamic tests have been carried out for increasing levels of seismic intensity applied at the base of the models in the three spatial components. The accelerations data recorded during the earthquake occurred in Norcia (Italy) on October 30th 2016 have been used as input. The building models have been instrumented with 10 uni-axial MEMS accelerometers, three sensors per-storey deployed in each plane in horizontal directions and one vertical direction installed at the base). The paper highlights the comparison between the two models performance, especially in terms of the response acceleration data and the damage state. 315 COMPDYN 2019 7 th ECCOMAS Thematic Conference on Computational Methods in Structural Dynamics and Earthquake Engineering M.

“…Up to date, the seismic behaviour of confined masonry walls/structures has been widely studied (e.g., Franch et al 2008, Marques and Lourenço 2013Ghorbani et al 2015;Perez et al 2015;Medeiros et al 2013;Janaraj and Dhanasekar 2014). The wall density significantly affects the seismic performance of masonry structuressuch as in terms of their seismic damage degree and ultimate failure mode.…”
