“…Several problems have been observed such as the in-plane/out-of-plane interaction in the seismic response of these non-structural elements (Figure 1a), the global influence in the overall seismic behaviour of the structure and the structural damages caused by local interaction between the masonry panels and the structural members (Figure 1b). The seismic behaviour of non-ductile masonry infills has been studied also experimentally and numerically into many researches that had different goals such as, the infill/structural global interaction ( [5], [6], [7]), the in-plane behaviour ( [8], [9]), the out-of-plane response ( [10], [11], [12]). The in-plane/out-of-plane interaction ( [13], [14], [15]), the economic evaluation of the expected annual losses ( [16], [17]) and the local interaction between the infill and the structural members ( [18], [19], [20]) as, for example, shown in Figure 2, were investigate as well.…”

The seismic vulnerability of rigidly attached masonry infills has been repeatedly highlighted through post-event surveys, experimental and numerical studies. Although many innovative solutions have been proposed, especially in the last decades, many aspects of these systems are object of ongoing or future studies. The ductile infills with sliding joints have been currently investigated by different researchers starting from experimental tests and using the test outcomes to calibrate and create finite element models with the aim to perform parametric analysis and define the local and global interaction with the structure. Moreover, the innovative infills with sliding joints have shown a completely different in-plane behavior with respect to the nonductile ones. Since the creation of the diagonal strut is avoided and the shear sliding mechanisms fostered in predefined sliding joints, the interaction between the masonry panel and the RC members represents novelty with respect to the "traditional" rigidly attached masonry solutions. Within the present paper the results of a numerical model calibrated according to inplane experimental tests are presented and the local interaction between the RC structural member and the innovative ductile infill with sliding joints is discussed. The study adopts a validated finite element model approach to an experimental campaign that has never been simulated through detailed FEMs and compares the numerical results with the experimental results related to the local effects.

“…e failure mechanism and the load resistance of the masonry-infilled RC frame depend on a number of parameters such as geometry of the wall (height/width ratio and openings), geometrical plane and elevation distribution of the infills in a structure, quality of the materials, stiffness and ductility of the frame, type of loading, detailing, relative infill-frame stiffness and strength, and quality of the workmanship. In a seismic event, however, they carry inplane shear loads or out-of-plane flexural loads [13,14]. Past earthquakes showed that the out-of-plane failures are more disastrous than the in-plane ones [15][16][17].…”

A numerical study was conducted to investigate the in-plane behavior of a masonry-infilled reinforced concrete (RC) frame retrofitted with textile-reinforced mortar (TRM). A two-dimensional finite element model was developed using DIANA finite element analysis (FEA) software to simulate the 2 : 3 scaled three-storey masonry-infilled RC frame retrofitted with TRM that was studied experimentally in the past. The three-storey structure used in the test was with a nonseismic design and detailing, and was subjected to in-plane displacement-control cyclic loading. The current study evaluates the capabilities of a representative numerical model to simulate the results of the experimental test, and after the calibration of the numerical model sensitivity analysis and parametric study were performed. In order to create an accurate numerical model, suitable constitutive models, based on the smeared crack approach, were used to characterize the nonlinear response of concrete, masonry infill, and TRM. The calibration of the models was based on the experimental results or inverse fitting based on optimizing the simulation of the response. The numerical model proved capable of simulating the in-plane behavior of the retrofitted masonry-infilled RC frame with good accuracy in terms of initial stiffness, and its deterioration, shear capacity, and cracking patterns. The calibrated model was then used to perform sensitivity analysis in order to examine the influence of infill-frame interface properties (tangential and normal stiffness) on the behavior of the retrofitted infilled frame. The numerical results showed that the gap opening is influenced significantly by the stiffness of the interface. In addition, a parametric study was performed in order to evaluate the importance of the full-bond condition between the TRM and the masonry-infilled RC frame. The numerical results indicate that the composite action between the TRM and the masonry-infilled RC frame improves the global stiffness and lateral resistance of the infilled frame, and it reduces the gap opening between the masonry infill and the RC frame.

“…It is known that masonry structures are vulnerable to both in-plane and out-of-plane movements under the action of lateral loads. The in-plane and out-of-plane behavior of the masonry infill has been studied experimentally [5] and numerically [6]. The out-of-plane failures turn out to be more disastrous than the in-plane ones [7].…”

“…The most recent retrofitting techniques include the use of fiber reinforced polymers (FRP) [18,19,20,21,22,23,24,25,26] ductile-fiber-reinforced cementitious composites (FRCM) [27,28,29] and textile reinforced mortar (TRM) [30,31]. TRM jacketing is an extremely promising solution for the strengthening of unreinforced infill walls subjected to either out-of-plane or in-plane loading [5]. In recent experimental and numerical studies provided by Koutas et al [32,33] the use of TRM for strengthening masonryinfilled frames was studied.…”

The behaviour of masonry-infilled reinforced concrete (RC) frame structures during an earthquake has attracted the attention by structural engineers since the 1950's. During the last decade, the use of textile reinforced mortar (TRM) as strengthening material for masonryinfilled RC frames under in-plane lateral loadings has been studied. This paper presents a numerical model of the behaviour of existing masonry-infilled RC frame strengthened with TRM that was studied experimentally at the University of Patras. It was a 2:3 scale three-story structure with non-seismic design and detailing, subjected to inplane cyclic loading through displacement control analysis. The objective of the present study is to identify suitable numerical constitutive models for each component of the structural system, in order to create a numerical tool to model the TRM strengthened-masonry infilled RC frames in-plane behaviour. A 2D TRM strengthened-masonry-infilled RC frame was developed in DIANA finite element analysis (FEA) software and an eigenvalue and nonlinear structural cyclic analysis were performed. There is good agreement between the numerical model and experimental results. It has been found that the numerical model has the capability to predict the initial stiffness, the ultimate stiffness, the maximum shear-force capacity, cracking patters and the possible failure mode of masonry-infilled RC frame with retrofitting. This model proves to be a reliable model of the behaviour of TRM strengthened-masonry-infilled RC frame under cyclic loading and can be used for further parametric studies.
