“…In this case the surfaces between which the fluid is located move with speed. Clutches (Qiu et al, 2022), brakes (Milecki and Hauke, 2012) 5(c). In this case, the surfaces between which the MRF is located may approach or move away from each other, causing fluid compression.…”

“…In this case the surfaces between which the fluid is located move with speed. Clutches (Qiu et al, 2022), brakes (Milecki and Hauke, 2012), and some types of vibration dampers are based on this principle. Squeeze mode (de Vicente et al, 2011; Ruiz-López et al, 2012), which is the least common, is shown in Figure 5(c).…”

Magnetorheological fluids (MRFs) are classified as intelligent materials whose rheological and mechanical properties can be modified by interaction with an external magnetic field. These unique features allow for a controlled change of their viscosity, which is applied in technology to build adaptive devices and effectively suppress vibrations in various mechanical systems. In this paper, we overview and discuss our previous results regarding advances and physicochemical MRF properties in the context of broader literature. We concentrated on such properties as flow, yield strength, and viscoelastic behavior under shearing flows. We briefly discussed continuum and discrete MRFs modeling. Since the magnetic core is mainly based on iron or its compounds, depending on its chemical composition, morphology, stabilizing agents, and the liquid medium’s viscosity, its rheological and micromechanical properties can be moderated. To predict the behavior of such a fluid, it is necessary to propose and implement an appropriate model. Simple models like Bingham can consider the quasi-static and dynamic behavior of the MRFs, while discrete models are applied to the development and implementation of the MRF control algorithms. Thus, analytical and numerical simulation compromise the accuracy, quantity of considered phenomena, and computational cost.

“…SMA materials are also usually used to improve the performance of dampers. Qiu et al [6][7][8] proposed several SMA-based dampers and studied their hysteretic behavior. Therefore, several researches have explored improving performance of isolation bearings by incorporating SMAs [9][10][11][12][13][14][15][16][17][18][19].…”

This paper proposes an adaptive friction isolation system (AFIS) composed of shape memory alloy (SMA) cables and double friction pendulum bearings (FPBs). Double FPBs with different friction coefficients enable two-level response characteristics that are advantageous at frequent and design basis hazard levels, while SMA cables with initial slack provide adaptive response at maximum considered earthquake hazard level. SMA cables are arranged vertically and they limit excessive isolation displacement by providing hardening effects and additional energy dissipation capacity. They also improve the stability of FPBs under severe earthquakes. Based on the experimental response of FPB and SMA cables, a high-fidelity finite element model of AFIS is first established in ABAQUS. Then, to study the effectiveness of the AFIS in controlling seismic response of structures, a simplified model of the AFIS is developed in OpenSees and nonlinear time history analyses of a seven-story steel frame building isolated with AFIS are conducted. The results show that the AFIS can satisfactorily meet displacement demands under frequent and moderate earthquakes, while it effectively reduces the excessive displacement of the building under severe earthquakes. In particular, the AFIS considerably improves the performance of the isolated building under pulse-like near-fault earthquakes.

“…No matter what kind of self-centering structures, they can be regarded as being functionally composed of self-centering elements and energy dissipation elements. In current research, the commonly used self-centering elements include pre-stressed tendons (Priestley et al 1993;Eldin et al 2019;Li et al 2021), pre-pressed disc spring components (Xu et al 2020;Yousef-Beik et al 2020;Dong et al 2019;Xue et al2021), and shape memory alloys (SMAs) (Ozbulut et al 2010;Gur et al 2013;Qzbulut et al 2016;Xue et al 2020;Wang et al 2020;Shi et al 2020;Qiu et al 2022;Zhang et al 2021;Shams et al 2021;Mirzai et al 2020;Wang et al2019). The common energy dissipation elements mainly include steel-based dampers (Eatherton et al 2014;Li et al 2021;Dong et al 2019), friction-based dampers (Eldin et al 2019;Xu et al 2020;Xue et al 2021;Ozbulut et al 2010;Gur et al 2013;Ozbulut et al 2016;Zhang et al 2021;Shams et al 2021;Mirzai et al 2020;Wang et al 2019;Westenenk et al 2019 ), and viscous fluid dampers (Kam et al 2010).…”

Previous researches on the constant ductility inelastic displacement ratio spectra (𝐶 μ ) of self-centering structures have been conducted based on the typical flag-shaped self-centering (FS) model. However, the arising shape-memory-alloy-friction self-centering structures (SMAFSs) own their specialized force-displacement relationship different from the typical FS model. In this research, a hybrid force-displacement model composed of the typical FS model and Coulomb friction model is employed and an efficient calculating procedure is proposed to statistically investigate the 𝐶 μ of SMAFSs. Comparison with the 𝐶 μ of the typical FS system with similar selfcentering capacity shows that the 𝐶 μ of the SMAFS is significantly different from that of the typical FS system, which explains the necessity of employing the hybrid model for SMAFSs and the effects of the friction. The effects of seismic parameters and structural parameters on the 𝐶 μ of SMAFSs are investigated. Furthermore, the formula for estimating the 𝐶 μ of SMAFSs is proposed through statistical regression. This proposed formula could estimate the 𝐶 μ of SMAFSs and describe the effects of structural parameters more accurately. The research could provide a basis of estimating the 𝐶 μ of SMAFSs to obtain reliable seismic design results of the structures.
