Mechanical modeling of superelastic tensegrity braces for earthquake-proof structures

Seismic Metamaterials With Tensegrity Architecture

“…In Figure . 2 of Ref. [3] the amplification properties of the 2D tensegrity bar have shown and quite high amplification has been seen. In this system of braces, the system can achieve extreme position, unlike the liquid viscous dampers.…”

“…It has been seen from the theoretical results published in Ref. [3] that the amplification factor of the 2D brace is enhanced when the SMA wires are incorporated. In addition, in the case of the 3D brace, it is possible to obtain even more important energy dissipation features with additional lateral buckling restraints, as shown in the Figure . 6.…”

“…In a special case of u/v = tanθ, β approaches to 0 i.e, β → 0, which signifies the negligible displacement from reference or original configuration. The variation of u/v with θ for different values of β is depicted in ref [3]. where u and v, denote the longitudinal and the transverse displacements of the structure respectively.…”

“…Also, in Figure 3 of Ref. [3], the experimental and theoretical results were obtained and compared. It can be observed that the experimental and theoretical results are nearly identical.…”

“…These structures are nowadays usually referred to as "mechanical metamaterials". It has been found that linear elastic meta-materials can exhibit peculiar behaviors in the dynamical regime, like,e.g., negative effective elastic moduli, negative effective mass density, phononic band gaps, to name just a few examples [7]. The seismic response of strongly non-linear meta-materials has been particularly investigated in this article.…”
