“…Only a few studies have investigated the structural behavior of such composite masonry walls [7][8][9][10]. An experimental campaign by the authors [11] encompassed tests on small and medium-scale homogeneous and composite walls in order to understand their behavior and investigate the influence of the interaction between thermal and masonry elements on the local resistance.…”

Since energy efficiency has become the main priority in the design of buildings, load-bearing walls in modern masonry constructions nowadays include thermal break elements at the floor–wall junction to mitigate thermal bridges. The structural stability of these bearing walls is consequently affected. In the present paper, a numerical study of the resistance and stability of such composite masonry walls, including AAC thermal break layers, is presented. A finite element mesoscopic model is successfully calibrated with respect to recent experimental results at small and medium scale, in terms of resistance and stiffness under vertical load with or without eccentricity. The model is then used to extend the numerical models to larger-scale masonry walls made of composite masonry, with the aim of investigating the consequences of thermal elements on global resistance and stability. The results confirm that the resistance of composite walls is governed by the masonry layer with the lowest resistance value, except for walls with very large slenderness and loaded eccentrically: composite walls with low slenderness or loaded by a vertical load with limited eccentricities are failing due to the crushing of the AAC layer, while the walls characterized by large slenderness ratios and loaded eccentrically tend to experience buckling failure in the main clay masonry layer.

“…(a) [3,13] (b) [14] The bearing capacity of conventional homogeneous masonry walls against vertical centered and non-centered compression has been investigated by many research studies via direct testing of masonry walls, e.g. [15][16][17][18][19][20][21].…”

“…The study pointed out that the compressive strength of the wallets was mainly governed by the resistance of the thermal layer but that an influence of the upper masonry units was also clearly identified. Another study by Mordant [13] has been carried out to investigate the behavior under static and dynamic lateral loads of masonry walls including a rubber layer at their bottom for acoustic reasons. It was concluded that the presence of this material has a favorable impact on the structural behavior in terms of failure mechanisms, energy dissipation and strain capacity.…”

“…In this perspective, the boundary conditions of simple cantilever beams are here updated in order to reproduce experimental configurations of specimens tested in the framework of the European FP7 project SERIES (Mordant et al, 2014). The specimens are four simple load-bearing clay URM walls with thin-layer glued bed joints and a tongueand-groove system as head joints.…”

Transverse vibrations of beams are an interesting topic for numerous engineering fields. The equations of motion develop under various assumptions and associate a frequency equation. This paper expresses the frequency equation for two specific models, using the Timoshenko beam theory. The first model is a typical cantilever beam with an additional mass attached to the free end. The second model considers a beam partially clamped at the base and with an elastic connection of the additional mass to the free end. The relevance of the used theory is discussed and the importance of each term of the equation is studied. These models find applications in unreinforced masonry. They are indeed fitted to identify, from white noise tests, equivalent mechanical properties of unreinforced load-bearing clay masonry walls including soundproofing devices in the perspective of modelling these elements with a macro-scale approach. Discrepancies with respect to current standards are underscored.
