“…For this purpose, low shear strength materials are usually applied in the horizontal sliding joints, such as steel plate, 15 corrugated steel sheet, 26 extruded elastomer, 27 wooden plank, 28 high damping rubber, 29 and modified asphalt waterproof 30 . Similarly, wooden planks with or without shear key, 31,32 multiple slit devices, 33 friction‐based devices, 34 steel tee energy absorbers, 35 steel cushions, 36 and mobile guide rail 37 are some optional choices to form the sliding joints for the vertical subpanels. Although the partitioned infills with sliding joints confirm low damage characteristics compared with traditional infills, the unexpected corner crushing or cracks of the infills once the drift ratio is higher than 3.0% still can be observed in literature at present, 38–40 which may inevitably lead to high repair cost after the earthquakes 41–43 …”

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.

“…This energy must be dissipated through the structure to prevent life and financial modern seismic design approach, a large portion of the imparted energy is expected to be dissipated through energy dissipation devices (EDDs). Many types of active [1][2][3] or passive [4][5][6][7][8] EDDs were designed and developed in academic and industrial areas to serve this purpose. Additional damping supplied by EDDs may reduce interstory drifts and shear forces through the structure reasonably [9].…”

A significant amount of seismic energy is imparted to the structures during earthquakes. The energy spreads within the structure and transforms in various energy forms as dissipated through the structure. The conventional seismic design provides specific ductile regions, namely plastic hinges, on structural elements. Therefore, the energy dissipation capacities of the structural elements and the structure enhance. However, this approach accepts that the deformations will concentrate on the plastic hinge zones and severe damage may occur on structural elements within deformation limits that are defined by the seismic codes. The modern seismic design aims to dissipate a large portion of the seismic input energy by installing energy dissipating devices (EDDs) to the structure. Thus, deformation concentrates on EDDs which can be replaced after an earthquake, and energy demand for structural elements is decreased. Lead extrusion damper (LED) is a passive EDD that utilizes the hysteretic behavior of lead. In this paper, the preliminary results of the developed three-dimensional finite element model (FEM) for a LED is presented. The results obtained from the finite element analysis (FEA) were compared with the experimental ones in which LEDs were exposed to sinusoidal displacements. Also, the applicability of the developed FEM was checked for different component dimensions given in the literature. The comparison study yielded a satisfactory consistency. Additionally, the maximum relative difference obtained for the literature devices was reduced to 12% from 39% by the developed FEM.

“…The embedded grooves were set in the wall to allow it to slip so that the interaction between the wall panel and the frame is reduced. Many scholars have focus on the energy absorption connectors, which can be used to improve the seismic performance of structures with the panel walls [7][8][9][10].…”

The multi-ribbed composite wall (MRCW) structure has the advantage of energy-saving, low weight, and adjustable stiffness. The partition, enclosure, and load-bearing capacity can be realized simultaneously. When the steel frame embedded and hung with the intercalated multi-ribbed composite wall (MRCW), the steel frame columns are avoided to expose in the air, so the durability and heat insulation performance of the structure can be improved. The steel frame is connected with the intercalated multi-ribbed composite wall (MRCW) by wet connection, and the mechanical property and the deformation mode of the multi-ribbed composite wall (MRCW) and steel frame are researched. The mechanical property of stud shear connectors is qualitatively and quantitatively analyzed, which is beneficial to improve the related design methods of structures.
