“…A highspeed railroad vibration isolation system employing NS elements was discussed in [22]. The authors in [23][24][25][26], employed structural NS elements at the basis of civil structures in order to suppress vibration without large force transmission to the superstructure during extreme earthquake excitations.…”

a b s t r a c tDespite the fact that the concept of incorporating Negative Stiffness (NS) elements within mechanical systems was formulated and validated more than 40 years ago, it has only recently received consistent attention. In this work, the design of a layered mechanical metamaterial having implemented NS inclusions is presented and its acoustic wave propagation properties are modelled. A dedicated twodimensional periodic structure theory scheme is developed in order to compute the frequency dependent damping loss factor of the metamaterial structure. The acoustic transmission properties through the modelled panel are computed within a Statistical Energy Analysis (SEA) scheme. It is demonstrated that the suggested layered metamaterial exhibits highly superior acoustic insulation performance close and above the acoustic coincidence range, thanks to the drastic increase of its structural damping properties implied by the NS elements. Additionally, the proposed configuration presents superior performance in a broadband frequency range when compared to a viscoelastic damping constraint layer of equivalent mass.

“…In addition, further investigations have been conducted by implementing the device on a quarterscale highway bridge model. The responses of the case with negative stiffness base isolator are significantly smaller than the original design (Attary et al, 2013(Attary et al, , 2014a(Attary et al, , 2014b(Attary et al, , 2015a(Attary et al, , 2015b. In civil engineering, the passive NSD designed by Iemura et al (2008) has been proposed for the vibration isolation of bridges and the testing result demonstrates clear reduction in absolute acceleration without significant displacement increment.…”

“…Its stiffness is changeable with displacement, which is negative when displacement is smaller than a threshold value, while increases dramatically if large displacement response occurs. One of a typical negative stiffness base isolators was designed and systematically investigated by Nagarajaiah and co-workers (Attary et al, 2013(Attary et al, , 2014a(Attary et al, , 2015bNagarajaiah et al, 2013;Sarlis et al, 2013Sarlis et al, , 2016, which takes full advantages of geometric lever structure and springs to realize negative stiffness in lateral direction. The negative stiffness will be triggered only when the displacement response is larger than the yield displacement of superstructure to keep it stable under small excitations, for example, wind.…”

In recent years, negative stiffness vibration isolation device with nonlinear characteristic has become an emerging research area and attracted a significant amount of attentions in the community due to the promising potentials it brought into the field. Its high-static-low-dynamic stiffness property endows the capacity to realize effective vibration isolation and in the meantime to maintain the system stability. This article presents a comprehensive review of the recent research and developments on negative stiffness vibration isolation device. It begins with an introduction on the concept of negative stiffness and then provides a summary and discussion regarding the realization and characteristics of negative stiffness vibration isolation device. The article places its special interest on the principles, structure design, and device characterisation of different types of negative stiffness vibration isolation devices, including spring type, pre-bucked beam type, magnetism type, geometrically nonlinear structural type, and composite structural type. Besides, the applications of negative stiffness vibration isolation device, as well as negative stiffness damper, are summarized and discussed based on the current state-of-the-art. Finally, the conclusions and further discussion provide highlights of the investigation.

“…Camara et al [83] proposed an approach to design optimum yielding dampers employing Triangular Added Damping and Stiffness (TADAS) dampers placed between the deck and supports, based on the equivalent SDOF approximation for short to medium span cable-stayed bridges in the transverse direction. Attary et al [84,85] evaluated the performance of Negative Stiffness Devices (NSD) for seismic response control of scaled highway bridge structures experimentally on a shake table using four different bridge configurations: 1) isolated bridge (IB); 2) NSDs+IB; 3) VD+IB; and 4) NSDs+VD+IB. The proposed NSD is shown in Fig.…”

This paper presents a state-of-the-art review of recent articles published on active, passive, semi-active and hybrid vibration control systems for structures under dynamic loadings primarily since 2013. Active control systems include active mass dampers, active tuned mass dampers, distributed mass dampers, and active tendon control. Passive systems include tuned mass dampers (TMD), particle TMD, tuned liquid particle damper, tuned liquid column damper (TLCD), eddy-current TMD, tuned mass generator, tuned-inerter dampers, magnetic negative stiffness device, resetting passive stiffness damper, re-entering shape memory alloy damper, viscous wall dampers, viscoelastic dampers, and friction dampers. Semi-active systems include tuned liquid damper with floating roof, resettable variable stiffness TMD, variable friction dampers, semi-active TMD, magnetorheological dampers, leverage-type stiffness controllable mass damper, semi-active friction tendon. Hybrid systems include shape memory alloys-liquid column damper, shape memory alloy-based damper, and TMD-high damping rubber.
