The latest earthquakes history shows that resistant conception, safe and economical structures are a daily challenge for structural engineers. Among the newest vibration control devices figures the inerter which is a device which can develop a large fictive mass (it consists of a mass amplification effect) using rotational inertia. In this research work, the effectiveness of a traditional passive tuned mass damper (TMD) is compared with a tuned mass damper inerter (TMDI) which consists generally of tuned mass damper coupled with an Inerter. Both devices are used to control a base-isolated structure vibration submitted to several seismic records. In This study, a base-isolated structure of six stories (6 DOF) was equipped with (TMD) and (TMDI) and a time history analysis were performed under different earthquake records (El Centro, Kobe, Kocaeli). The mathematical model of the building is established in MATLAB Simulink. The simulation results illustrated he robustness, performance and effectiveness of the structure equipped with a (TMDI). The dynamical parameters of interest were base and top displacement as well as the base shear force and peak inerter force produced.

“…SMA dampers are also used in cable bridges to reduce the vibration of cables 35–39 . To develop a hybrid damping system, SMA material is used with conventional linear and nonlinear dampers (such as viscous damper, friction damper, and metallic yield damper), which show a very high level of energy dissipation capacity under the cyclic loading and self‐recentering capability 28,40–42 . Some of the very recent studies tried to assess the failure vulnerability (using fragility analysis) of structures supplemented with SMA devices, and they show superior control efficiency over the existing convention dampers, resulting in the reduction of failure probability 27,43–45 …”

Summary The use of supplemental damping for mitigation of seismic hazard of adjacent building structures is proven to be a practical and efficient way. In developing an efficient damper/energy absorber, shape memory alloy (SMA) material is an excellent candidate due to its well‐known high‐energy dissipation capacity via thermomechanical‐phase transformation. For the first time, the present study focuses on the seismic response control efficiency of superelasticity SMA damper over conventional yield damper, for vibration control of adjacent building structures. To this end, the response of two adjacent steel building frame structures connected with SMA and yield dampers is evaluated through nonlinear dynamic time‐history analysis, under a set of recorded near‐fault ground motions. Optimal characteristics of both dampers are obtained through a parametric study. The robustness of the improved performance of the SMA damper over the yield damper is studied for various characteristic damper strengths, building structures, as well as different scenarios of seismic loading. It is being demonstrated that the superelasticity SMA damper significantly improves the floor displacement control efficiency over the yield damper and also provides a considerable amount of reduction in the peak value of the absolute floor acceleration.

“…Parulekar et al (2012) made an analytical study of a supporting steel structure of dump tanks with and without SMA dampers.

Nickel Titanium (Ni-Ti) Shape Memory Alloy (SMA) can be used to limit response of structure during external disturbances such as large seismic events. This paper presents a seismic performance study of Ni-Ti SMA wires equipped in the spatial skeletal structure. First, an improved Graesser-Cozzarelli (G-C) numerical constitutive model of the Austenitic phase of NiTi SMA wire is established. By contrast, the model based on uniaxial cyclic loading experimental tests is demonstrated as feasibility and validity. Next, a method consisting of a three-layer steel spatial skeletal structure model equipped with SMA wires is employed for simulation and experimental tests. According to the obtained constitutive numerical model, the simulation program of vibration control is written to simulate the effect of vibration control of seismic EL-centro wave. Furthermore, a shaking table experimental test was designed to verify the vibration control effect under the same action of seismic EL-centro wave. By comparison of the results of the numerical simulation and shaking table test, dynamic responses of the displacement and acceleration for different floors with control and without control was concluded. The superior superelastic properties of SMA wires used in passive control are investigated and the correctness of the constitutive numerical model are verified as well. The results show that such a comprehensive analysis integrates seismic-resistant behavior of Ni-Ti SMA wires in this type of structure. Besides, proposed method has broad application prospects to address the issues in passive control field of building structures.
