To realize the prefabricated structure of special‐shaped concrete‐filled steel tubular (CFST) column frame and enhance the level of indoor room utilization, this paper proposed a novel prefabricated frame with special‐shaped CFST columns and H‐shape steel beams connection with side plate. To investigate seismic behavior of this prefabricated frame structure, a 2‐story and 2‐bay CFST frame specimen was fabricated and tested under reversed cyclic loading. The failure mode, hysteresis behavior, degradation of lateral stiffness and bearing capacity, ductility and energy dissipation were analyzed. Experiment results indicated that failure mode presented strong columns and weak beams. Hysteresis curve of frame showed fully shuttle‐shaped. The mean story drift angle was 1/36 at ultimate stage. Equivalent viscous damping coefficient was 0.038–0.464. The bearing capacity degradation was relatively gentle, but the overall stiffness degradation was more obvious. It suggested that the frame had proper seismic and energy dissipation property. After the test, the seismic property of test frame was further investigated through the numerical simulation approach. The failure mode and skeleton curve obtained from the simulation were nearly consistent with test results, indicating that numerical analysis results were precise and with high reference meaning.

“…Experimental and numerical studies have effectively characterized the mechanical behaviour and dynamic responses of self-centering systems, as evidenced by recent research [8][9][10][11]. However, obtaining a complete picture can be both time-consuming and costly, and the results are often not continuous.…”

A resilient system comprised of a high-strength moment-resisting steel frame (HS-MRF) and self-centering steel plate shear walls (SC-SPSWs) has been proposed to address the issue of frame expansion. The system's steady-state dynamic responses were analysed using an analytical solution of a single-degree-of-freedom nonlinear oscillator under harmonic excitation, solved via the method of slowly varying parameters. A stability analysis was also conducted to assess the behaviour of singular points. The hysteretic model for the proposed structure is a combination of validated bilinear, self-centering, and pinching hysteresis, representing the high-strength frame, self-centering frame, and steel plate shear wall, respectively. The results indicate that increasing the proportion of bilinear hysteresis has minimal impact on resonance but can decrease nonlinearity for lower excitation intensities. However, for higher intensities, increasing the bilinear hysteresis can significantly decrease peak responses and reduce both the jump and unbounded phenomena. Most of the unstable responses can be divided into four zones, and the unstable regions are greatly influenced by the ratio of hysteretic models. This steady-state dynamic analysis suggests that a well-designed mixture of high-strength moment-resisting steel frames and self-centering steel plate shear walls can bring a favourable seismic performance.
