The tuned vibration absorber (TVA) provides vibration reduction of a primary system subjected to external excitation. The idea is to increase the number of system degrees of freedom connecting a secondary system to the primary system. This procedure promotes vibration reduction at its design forcing frequency but two new resonance peaks appear introducing critical behaviors that must be avoided. The use of shape memory alloys (SMAs) can improve the performance of the classical TVA establishing an adaptive TVA (ATVA). This paper deals with the nonlinear dynamics of a passive pseudoelastic tuned vibration absorber with an SMA element. In this regard, a single degree of freedom elastic oscillator is used to represent the primary system, while an extra oscillator with an SMA element represents the secondary system. Temperature dependent behavior of the system allows one to change the system response avoiding undesirable responses. Nevertheless, hysteretic behavior introduces complex characteristics to the system dynamics. The influence of the hysteretic behavior due to stress-induced phase transformation is investigated. The ATVA performance is evaluated by analyzing primary system maximum vibration amplitudes for different forcing amplitudes and frequencies. Numerical simulations establish comparisons of the ATVA results with those obtained from the classical TVA. A parametric study is developed showing the best performance conditions and this information can be useful for design purposes.

“…There are different ways to describe the SMA behavior, see e.g. Lagoudas (2008) and Paiva and Savi (2006) for an overview of constitutive models. Here, a constitutive model with internal variables previously discussed in different references (Savi et al, 2002b;Baêta-Neves et al, 2004;Savi and Paiva, 2005;Monteiro et al, 2009;Aguiar et al, 2010;Oliveira et al, 2010) is employed.…”

“…In order to simulate material behavior of SMAs numerically, microscopic methodology and macroscopic methodology are two approaches which focus on molecular level and phenomenological features of SMAs, respectively Paiva and Savi [9]. Phenomenological models are gotten more interests for their simplicity and suitability in seismic engineering application.…”

ABSTRACT:In this paper, the effectiveness of seismic performance upgrading is studied by adoption of damping devices made of shape memory alloys (SMAs). An axial-type SMA damper is constructed and modeled on the basis of a modified multi-linear one dimensional constitutive model of SMAs. Time history analyses are carried out on typical steel frames with SMA damping devices. Performance parameters for seismic performance upgrading are investigated in consideration of four influence factors, i.e., strength ratio, martensite fraction, length ratio, and ground motion. Dynamic analyses of bare frames and frames with equivalent BRB dampers are also conducted for comparisons. Numerical investigations show that excellent re-centering ability and energy dissipation can be afforded by installing SMA damping devices in structures.
