“…The seismic vulnerability of frame-reinforced concrete (RC) structures due to infill frame interaction has been observed repeatedly (EERI 1996(EERI , 2000Hermanns et al 2013) and is well acknowledged in the literature (Paulay and Priestley 1992;Fardis et al 1999;Dolšek and Fajfar 2008). Typically, infill walls have so far been proportioned and verified as nonstructural elements of the building and their role in the structural response has often been underestimated or completely neglected in design practice.…”

The paper presents the results of an experimental campaign on the behaviour of engineered masonry infill walls subjected to both in-and out-of-plane loading. The aim of the research was to develop a design approach for masonry infill walls capable of solving their vulnerability and detrimental interaction with the frame structure when exposed to seismic excitation. Tests on two large-scale specimens and sub-assemblies were performed in order to evaluate the infill deformation capacity, the damage associated with different drift levels, and the mechanical properties of the components. A design solution with sliding joints to reduce the infill-frame interaction and ensure out-of-plane stability, which was proposed in a previous study, was developed and refined with focus on construction details. The aim of sliding joints is to ensure a predetermined mechanism in the infill wall, which is governed by hierarchy of strength and is capable of ensuring ductility and energy dissipation that can be taken into account in the design practice, thanks to the predictability of the response. The two infill wall specimens, one of them including an opening, reached up to 3 % in-plane drift with very little damage and supported an out-of-plane force equivalent to a horizontal acceleration four times the acceleration of gravity. The force-displacement hysteretic curve, sliding at the joints and crack pattern show the efficiency of the construction technique, based on affordable and tradition-like construction processes and materials. The technique, presented here for hollow fired-clay masonry units, can be extended to different masonry infill typologies.

“…They are generally constructed for residential and commercial purposes. In recent years, negative effects have been observed in recent earthquakes, for example, in 2014 Mae Lao earthquake [4], 2011 Lorca earthquake [5], 2009 L' Aquila earthquake [6,7], 2008 Wenchuan earthquake [8], 2007 Pisco-Chincha earthquake [9], and 2006 L' Aquila earthquake [10], which highlighted the vulnerability of RC frames with infill walls.…”

The expansive polystyrene granule cement (EPSC) latticed concrete wall is a new type of energy-saving wall material with loadbearing, insulation, fireproof, and environmental protection characteristics. A series of shaking table tests were performed to investigate the seismic behavior of a full-scale reinforced concrete (RC) frame with EPSC latticed concrete infill wall, and data obtained from the shaking table test were analyzed. The experimental results indicate that the designed RC frame with EPSC latticed concrete infill wall has satisfactory seismic performance subjected to earthquakes, and the seismic responses of the model structure are more sensitive to input motions with more high frequency components and long duration. The EPSC latticed concrete infill wall provided high lateral stiffness so that the walls can be equivalent to a RC shear wall. The horizontal and vertical rebar, arranged in the concrete lattice beam and column, could effectively restrain the latticed concrete infill wall and RC frame. To achieve a more comprehensive evaluation on the performance of the RC frame with latticed concrete infill walls, further research on its seismic responses is expected by comparing with conventional infill walls and nonlinear analytical method.

“…Recent earthquakes have shown that the out-of-plane failure of infills can occur even for moderate intensity of the ground motion [1,2,3]. For this reason, the interest in the out-ofplane behaviour of infill walls has been growing in the last years.…”
