“…8 However, capturing the actual seismic responses of frames with infill walls constructing door openings is challenging, as most seismic design specifications do not adequately account for this intricate interaction during the structural design process. [9][10][11] To mitigate the detrimental infill-frame interaction, three solutions are of most interest currently [12][13][14][15] : strengthening the infill wall, decoupling the infill wall from the surrounding frame, and incorporating a sliding mechanism into the infill wall. Although enhancing the infill wall through rebars 16 or fiber-reinforced polymers 17 would alleviate its vulnerability, such a method may exacerbate the adverse infill-frame interaction by increasing strut forces of the infill walls on the structures.…”

Semi‐rigid steel frame stands out due to its remarkable deformation capability under seismic loading, while the introduction of partitioned walls would disturb the expected seismic behavior of the infilled steel frames. Furthermore, the presence of door openings might exacerbate these negative effects. To mitigate the detrimental multiple‐diagonal strut effect of traditional infill walls around the door opening, an innovative low‐damage wall panels system: prefabricated infill wall panels with a door opening and sliding joints are presented for semi‐rigid steel frames. For testifying the effectiveness of the proposed structure, a quasi‐static test was carried out on three half‐scaled steel frames: a bare frame, a frame infilled with conventional wall panels with a door opening, and a frame infilled with the novel wall panel system with a door opening. Experimental results reveal that the developed innovative wall panels with a door opening could avoid unfavorable crack developments and opening deformation around the door area. It is mainly attributed to the releasement of the adverse multiple‐diagonal strut mechanism of traditional wall panels with door openings. Thus, the presented infilled frame showcases seismic performance similar to the bare steel frame, while having a higher energy dissipation capacity. Moreover, the developed analytical prediction method based on the superposition principle could accurately estimate the lateral load‐carrying capacity of the structures. Due to negligible deformation of the both bottom infill wall panel and the door opening, the innovative infill wall only contributes about 10% lateral load‐carrying capability to the infilled frame.

A cantilever block-wall panel attachment strip (CBW) flexible connection node was designed to connect precast concrete (PC) exterior wall panels to steel frames. To investigate the performance of the CBW flexible connection node and PC exterior wall panels during earthquakes, a partial two-storey steel frame was extracted from an actual engineering structure, and a full-scale steel frame-exterior wall panel shaking table model was designed. Two sets of shaking-table tests were conducted under seismic intensity 7, 8, and 9 (Chinese Seismic Intensity Scale) earthquakes. The acceleration and displacement responses of the composite wall panel, open window panel, and integral wall panel along the in-plane and out-of-plane motions were analysed. The acceleration amplification factors of the PC exterior wall panels ranged from 0.753 to 1.400 (in-plane) and from 0.998 to 2.199 (out-of-plane). The CBW flexible connection node had a deformation capacity that could coordinate the deformation of the exterior wall panel and prevent severe damage. The surfaces of the PC exterior wall panels remained intact during a very strong seismic intensity 9 earthquake.

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.
