“…Similarly, Saheb et al conducted experiments on single-layer, single-span specimens and performed performance analysis to enhance the connection method between frame and infill walls, achieving effective filling. The research method ensured intact filling with positive application effects [8]. Davorin et al focused on investigating the role of masonry infill walls in the shear bearing capacity of frames, particularly examining the impact of different types of openings on individual component performance.…”

To reasonably evaluate the overall seismic performance of infilled wall frames, a corresponding nonlinear analysis model is constructed with infilled wall frames as the research object. It quantifies the failure levels of structural and non-structural components and proposes a method for extracting structural overall performance indicators. The vulnerability of the case frame structure is analyzed using the Incremental Dynamic Analysis (IDA) method. The results showed that the seismic performance of the infilled wall frame and the ordinary frame met the seismic fortification requirements, and the seismic capacity of the infilled wall frame was better. After implementing a 7-degree seismic fortification, the cumulative probability of basic integrity, minor damage, and moderate damage for infill wall frames reached 99.15 %, surpassing the fortification target of 1.5 g. However, the seismic capacity of ordinary frames was overestimated, as their cumulative probability of basic intact, minor damage, and moderate damage under a 7-degree seismic fortification was 99.7 %. Neglecting its impact, ordinary frames exhibited lower seismic performance compared to other structures, with a basic intact probability of only 48.49 % under frequent earthquake actions at 7 degrees. The research utilizes effective methods for evaluating the seismic vulnerability of infilled wall frames.

“…To eliminate the adverse multiple diagonal struts effect of the infill walls, the idea of the next method is to uncouple the infill from the primary structure by cutting off the corner of the wall panels 15 or application of flexible joints around the wall‐frame interfaces. The favorable materials for the flexible joints in the separation gaps include the rigid‐brittle element, 16 perforated autoclaved aerated concrete block, 17 cellular polyethylene plate, 5 Styrofoam, 18 polyurethane foam, 19 U‐shaped elastomer, 20 cellular material, 21 deformable matrix material, 22 grooved lead, 23 stone wools, 24 and steel connectors 25 .

The detrimental infill‐frame interaction and vulnerable nature of the traditional solid infill walls might change the seismic behavior of the infilled reinforced concrete frames. To mitigate the adverse infill‐frame interaction and protect the fragile infill walls, in this paper, an innovative solution by partitioning the infill wall panels with low‐strength mortar sliding joints and uncoupling the infill from the boundary frame by flexible materials is presented for the reinforced concrete frames. Three 1/2 scale specimens designed in this context were examined experimentally and numerically, and a simplified model is developed for the proposed infill system. Test results show that the presented low‐damage infill system could effectively mitigate the adverse infill‐frame interaction and considerably prevent corner crushing or damage to the infill wall panels so that the reinforced concrete frame with the proposed infill system behaves similarly to the bare frame. Thanks to the working mechanism of the infill system, the proposed wall panels have a relatively high energy conversion efficiency from inter‐story displacement to the energy dissipation capacity of the infilled frame. Moreover, the developed simplified infill model could well capture the hysteretic behaviors of the proposed low‐damage infill system and improve the calculation efficiency. Parametric analysis results indicate that the friction factor of the sliding joints plays a significant role in enhancing the seismic behavior of the novel low‐damage infilled system.
