“…High-rise buildings need more brittle infill panels. Infill panels connected only with HBEs dissipate less energy and carry less load than fully connected infill panels but demonstrate the same lateral deformation resistance [24][25][26]. SPSW infill's ductility and post-buckling strength provide seismic stability.…”

“…Elongation of the ring shrinks the diagonal links during tension, preventing the web from sagging perpendicular to the tension field [30,31]. Low-rise buildings subjected to near-field ground motions showed the best performance from unstiffened SPSW systems, whereas RS-SPSW and honeycomb-SPSW systems demonstrated good resistance to induced structural acceleration and dampening effects [26]. Prior to suggesting a new and improved configuration of MSCSS that addresses common problems faced by structural engineers in high-rise building design, in this research, plastic deformation and plastic and viscous dissipation in various MSCSS configurations under seismic loads are studied.…”

This paper seeks to examine the plastic deformation and seismic structural response of a mega-subcontrolled structural system (MSCSS) subjected to strong seismic excitations. Different MSCSS configurations were modeled with nonlinear finite elements, and nonlinear dynamic analyses were performed to examine their behaviors. This paper introduces a novel and optimized MSCSS configuration, configuration 30, which demonstrates remarkable results for the reduction of plastic strain. Utilizing a steel plate shear wall enhances the seismic structural integrity of this system (SPSW). This configuration improved the mean equivalent plastic strain of columns and beams by 51% and 80%, respectively. In addition, a comparison between unstiffened and ring-shaped infill panels of SPSWs demonstrates that ring-shaped infill panels offer greater lateral stiffness and energy dissipation with a 44% reduction in maximum equivalent plastic strain. Compared to configuration 1, configuration 30 exhibited the most controlled structural response, as the minimum residual story drift improvement was 70% in the first, second, and third substructures, respectively, and the maximum coefficient of variation (COV) was 16% and 32% in the acceleration and displacement responses, respectively.

Shear wall structure is one of the options as an appropriate lateral load-bearing system for new structures or as a means of retrofitting existing buildings. There are many types of shear walls, including steel plate shear walls (SPSWs). In enhancing its function, a thin SPSW is added with a stiffener. However, steel shear walls with stiffeners increase construction costs due to the time-consuming factor and the high cost of welding thin plates. Therefore, the infill shape was modified to increase the energy dissipation capacity of the SPSW. This study conducted simulations by varying the geometry, mesh, load factor, and materials used in SPSW. The specimen was modeled and tested using the ABAQUS application’s finite element analysis. The simulation was done by ignoring welded joints, fish plates, and bolts. The result that was the output of the simulation was hysteresis behavior. In addition, the contours that occurred were also observed in this study. The H1 shape had the best hysteresis force–displacement graphics among the nine other geometric shapes. Ten mesh sizes were tested, starting from 25 mm and increasing by multiples of 10 up to 115 mm. The results showed significant differences, with a 33.3% increase at the 115 mm size, which was considered irrational. The load factor represented the applied load in each substep, and a load factor of 2 means the load was doubled compared to a load factor of 1. Seven materials were tested, and high carbon steel outperformed others as it can handle loads up to 1,000 kN, demonstrating excellent energy dissipation capabilities.
