Infilled wall is a primary structure which is used in a multistorey RC-framed structure. It is not designed like structural elements, but it is subjected to structural load and response as a heavily damaged element into the building. The main problem of an infilled wall is not actively utilizing in the framed structure and it is not interacted with frame elements. The objective of research is to utilize the infilled wall in the RC-framed structure by improving its performance of behavior. Here, two different types of brick masonry like Autoclaved concrete and clay brick masonry were used as the infilled wall in an RC-framed structure. A singly bay and single storey RC framed structure was cast and tested under a 1/10th scale model by diagonal compressive loading. The specimen was subjected to static loading by a universal testing machine. Infilled wall is weak in tension, so a reinforcing band was used to improve the performance like load carrying capacity, stiffness, ductility, and energy dissipation capacity. Based on the results of the experimental study, it is found that reinforcing band with the infilled wall gives better behavior of the RC-framed structure.

“…Among these, diagonal tension may not be considered a failure (Moretti 2015), and compression at the corner is similar to diagonal compression failure. It is found in numerous literature that most of the infill panel shows sliding shear failure (Seki et al, 2018, Celano et al, 2021, Zovkic et al, 2012 and compression at the center of the panel (Kaya et al, 2018, Essa et al, 2014, Alwashali et al, 2017. Hence only these two failure mechanisms have been considered herein and the compressive strength (𝑓 ) corresponding to sliding shear and compression at the center panel is computed as per equation (1) and equation (2), respectively.…”

Bangladesh which lies in an earthquake-prone region, possesses many seismically vulnerable structures and would need to be strengthened for future usage following the current building code. In this context, assessing the responses of the existing building frames with or without infilled masonry is essential for designing an adequate strengthening scheme that would be suitable for the building. The current study intends to model and simulate one of the available masonry infilled test specimens where the fiber modeling approach of RC member and the multi-strut model of infill masonry have been considered. In addition, the numerically obtained lateral strength has also been compared with analytically evaluated lateral strength. The lateral responses obtained from the numerical analysis showed a fair agreement with the experimental cyclic behavior having a ratio of experimental to the numerical lateral capacity of 0.97. The numerical lateral strength also indicates good conformity with analytical evaluation having an analytical to numerical lateral capacity ratio of 1.13.

“…Thus, it is required to examine the impacts of infilled walls on stiffness despite the ignorance of their resistance. Stiffness is the rigidity of a structural element the extent to which it resists plastic deformation against applied load [9]. The initial stiffness of every numerical model was calculated by displacement-based design (DBD) method [18] described as follow:…”

Masonry infilled walls are widely used in reinforced concrete (RC) frams worldwide. However, infilled RC frame building failure is a common mode in destructive earthquakes. Further researcher is needed to bring insightful understandings into the behaviors of these structures. Therefore, this study investigates seismic parameters, ultimate tensile damage, and force transfer mechanisms in a reinforced concrete structure under in-plan load. For this purpose, the definitions and the relevant literature were reviewed. Then, an analytical software supporting an infill model was selected and described altogether with a particular modeling approach. Calibrating software results with those presented by Abdulhafez et al. (2014), the researchers designed a series of planer one-story one-bay reinforced concrete frames upon ACI 318M-14 Building Code. The seismic behavior of infilled frames were also studied using finite element method. Force transfer mechanisms in infilled frame with opening, which is one of the important items, was investigated in this study. Comparing the analysis outcomes with the bar frame, it was indicated that the ultimate load, stiffness, and toughness of the full in-filled frame were increased while the ductility was decreased. It was also revealed that the presence of opening in infilled frame decreased the ultimate load, stiffness and toughness corresponding full infilled frame. In addition, the increasing of opening size increased the reduction of the ultimate load, stiffness and toughness.
