Shape memory alloys and their application in structural oscillations attenuation

The paper investigates the benefits that the SMA-behaviour can introduce in the dynamical response of a structural system. fluence of SMA tendons contributing to the overall strength of a simple elastic–plastic structural model undergoing horizontal shaking and subject to vertical loads is firstly analysed, proving that coupling super-elastic members with elastic–plastic structures yields an excellent performance in attenuation both of the P–Δ effect and of the final residual deformation. second investigation, this system is looked at as an isolation device and is introduced in a m.d.o.f. elastic–plastic structural model; its attitude in suppressing plastic deformations in the super-structure is demonstrated.
