1. Introduction
. Introduction In recent years, various design philosophies have been developed to reduce the economical losses and inelastic deformations of structures under strong ground motions. After the 1994 Northridge earthquake, supplemental energy dissipation devices have been introduced to improve the resistance of structures. A wide range of materials can be used in passive energy dissipation systems to improve the structural responses [1, 2]. Examples of such systems are viscoelastic devices, buckling-restrained braces (BRB) and friction dampers. In spite of several advantages of energy dissipation devices, relatively large residual displacement is the major deficiency in these systems. Moreover, current technologies demonstrate some restrictions including problems related to temperature dependence performance, serviceability and resilience and complications related to installation and substitution. Application of SMA-based self-centering systems received signifi- cant attention from scholars and designers recently. SMAs are unique class of alloys with capability to recover their original shape upon unloading (Superelastic Effect‐SE) and heating above a transformation temperature (Shape Memory Effect‐SME) [3]. The striking characteristics of SMAs can be attributed to thermal effect or stress-induced phenomenon. Considering its exclusive properties, SMA wire is used as a core recentering component in the SCHD. Several numerical and experimental studies have shown the workability of SMAs in vibration mitigation of structural systems. Desroches and Delemont [4] have investigated the effectiveness of SMA bars to hinder unseating of the bridge deck from the pier. A modern base isolation system composed of steel-teflon flat sliding bearings was proposed by Jalali et al. [5]; they used SMA truss elements to provide a proper restoring capability. Besides, Cardone et al. [6] conducted an experimental investigation of the Smart Restorable Sliding Base Isolation System (SRSBIS) using superelastic Shape Memory Alloy (SMA) wires, and the outcomes revealed that the SRSBIS can be reliably used in passive control of structures. Dolce et al. [7] evaluated the effectiveness of SMA braces in reinforced concrete structures, results from shaking table test demonstrated that SMA bars can provide favorable self-centering capability. In addition to the mentioned applications, SMAs gained widespread popularity in framed structures. Dolce et al. [8] tested special types of braces using promising properties of SMA during the ‘Memory Alloys for New Seismic Isolation and Energy Dissipation Devices’ project, the working mechanisms of the device verified the new design concept. Ozbulut and Hurlebaus [9] introduced a recentering variable friction device for vibration limitation of structures subjected to near-field excitations. Simulation results demonstrate that the proposed device has the capability to reduce the peak structural response. Zhu and Zhang [10] investigated the seismic response of a concentrically braced frame (CBF) with reusable hysteretic damping brace made of energy-dissipating SMA wires, results show that the proposed system has a potential to eliminate the residual interstory drift. In another study, Zhu and Zhang [11] suggested a type of bracing element
