“…A group of solutions is based on decoupling techniques between masonry infill and frame so that the deformations of the latter do not generate stress on the panel (e.g., Nasiri and Liu, 2016;Tsantilis and Triantafillou, 2018;Marinković and Butenweg, 2019). Another approach consists in reducing the infill-frame interaction through the use of sliding or deformable joints, which concentrate the IP deformation and damage in selected planes, keeping the infill panel undamaged even if in contact with the surrounding frame (Mohammadi et al, 2011;Preti et al, 2015;Verlato et al, 2016;Vintzileou et al, 2016;Morandi et al, 2018b). However, a general consensus has not yet been reached on any of these innovative solutions, presenting all some pros and cons in terms of seismic, thermal, and acoustic performances, as well as durability and cost.…”

This paper presents an overview of the experimental results obtained by combined in-plane/out-of-plane (IP/OOP) tests carried out on robust clay masonry infill walls. The combined tests were carried out on eight full-scale one-bay, one-story infilled reinforced concrete (RC) frames, plus one reference RC bare frame. In four cases, the masonry walls fully fill the RC frame: two walls are made of unreinforced masonry (URM), whereas the other two are made of reinforced masonry (RM), with both vertical and horizontal reinforcement. Each pair of specimens was tested up to different levels of IP drift before carrying out the OOP tests. Four other specimens, still made of URM and RM walls, are characterized by the presence of a central opening, and in one case, the effect of a lintel is analyzed. On the basis of the tests carried out, an analytical model was developed for the analysis of the OOP behavior. It was used to calibrate IP damage degradation models based on the experimental results to define limits for the applicability of well-known flexural and arching mechanism models for the evaluation of the OOP capacity of the infill walls and to evaluate the efficiency of vertical reinforcement. In this work, the experimental campaign is presented, and the results of both experimental tests and numerical analyses are discussed.

“…With reference to the principles of this last typology, the masonry section research group of the University of Pavia, involved in the European FP7 research project "INSYSME" [12], and of the University of Newcastle (Australia) have developed and implemented two different innovative pliable masonry infill systems: one mortar-less made of specially shaped masonry units capable of sliding on all bed-joints (Lin et al [13]); another with an infill masonry panel subdivided into several horizontal sub-panels using specially engineered sliding joints (Morandi et al [14]). Other different solutions with "weak plane" joints have also been recently developed within the "INSYSME" project by other researchers (e.g., Verlato et al [15] and Vintzileou et al [16]) or in other studies (e.g., Mohammadi et al [17], and Preti et al [18], [19]).…”

Many post seismic event inspections and studies conducted by different researchers have identified the threat to human lives and considerable economic losses related to the damage sustained by "traditional" masonry infills. Although several innovative infill solutions and new design approaches have been proposed, a viable practical and universally accepted solution has not been achieved yet. Among the very promising designs, according to the ongoing studies, are pliable infill panels with the in-plane stiffness reduced and the displacement ductility increased compared to "traditional" infills. One way to attain such a significant pliability of a masonry infill is to divide it into a number of segments interconnected through horizontal sliding joints. The research units at the University of Newcastle (Australia) and the University of Pavia have proposed and are studying two different infill systems of this type: one mortar-less made of specially shaped masonry units capable of sliding on all bed joints; another with infill masonry panel subdivided into several horizontal sub-panels using specially engineered sliding joints. Within this paper, two systems are compared and discussed with particular emphases on their basic dynamic characteristics required for seismic analysis.

“…Lastly, a more recent series of works studied the combined IP/ OOP behavior of more robust, eventually internally reinforced with steel bars, clay masonry infill walls (da Porto et al 2013;Vintzileou et al 2016;Palieraki et al 2018), and a consistent number of works has focused on the development of innovative solutions to increase the infill wall ductility and/or decrease the infill wall/RC frame interaction (Mohammadi and Akrami 2010;Mohammadi et al 2011;Baio Dias et al 2014;Preti et al 2015;da Porto et al 2016;Verlato et al 2016;Morandi et al 2018;Marinkovic ́and Butenweg 2019).…”

This paper presents an overview of the experimental results obtained by combined in-plane/out-of-plane (IP/OOP) tests carried out on reinforced concrete (RC) frames infilled with thin clay masonry walls. After preliminary characterization tests on building materials, combined IP/OOP tests on eight full-scale, one-bay, one-story infilled RC frames were carried out. Three external strengthening solutions were investigated considering three types of lime-based plasters, reinforced by means of dispersed fibers and/or bidirectional basalt meshes, applied on both sides of each wall. The experimental results of the tested frames are presented, discussed, and compared to evaluate the performance and the effectiveness of each strengthening solution.
