“…The recentering group consists of the two sets of austenite wires A and B, which are in tension only and react in reverse directions because the austenite wires A and B have excellent superelastic ability with relative small hysteretic loop, as shown in Figure 3(b)- (1) and Figure 3(b)- (2). And the energy dissipation group is made up of the martensite sheet that is restrained so that it can afford tension and compression without undergoing buckling and its good energy dissipation ability is as shown in Figure 3 Like SMA dampers developed by Dolce et al [2] and Zhu and Zhang [6] mentioned above, two groups, i.e., recentering group and energy dissipation group, are designed in the axial-type SMA damper. Corresponding to a pair of pre-tensioned SMA wire systems in the damper by Dolce et al and a friction sliding surface design in the damper by Zhu and Zhang, the restrained martensite sheet is the energy dissipation group in the proposed damper of this study.…”

“…Moreover, two sets of austenite SMA wire systems are set as recentering group that is similar to both the dampers. The damper by Zhu and Zhang [6] is improved from the damper by Zhu and Zhang [5] that a friction design is added to increase energy dissipation. Compared to the damper by Dolce et al, a restrained marteniste sheet instead of pretensioned wire systems is adopted in the damper to dissipate energy.…”

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.

“…2.b shows another possible implementation [19] using two steel elements and two sets of SMA wires anchored in such a way so that relative displacement between the steel elements will produce tension in one of the two sets of SMA wires. A slot cut on the bottom steel element permits the relative displacement between the two steel elements while additional energy dissipation is provided with friction at the interface.…”

This paper highlights the role of advanced structural analysis tools on the conception of high-performance earthquake-resistant structural systems. A new steel frame equipped with self-centering devices and viscoelastic dampers is described. A prototype building using this frame is designed and a detailed nonlinear analytical model for seismic analysis is developed. Seismic analyses results show the effectiveness of the proposed frame to enhance structural and non-structural performance by significantly reducing residual drifts and inelastic deformations, and by reducing drifts, total floor accelerations and total floor velocities. These results are the basis for further studies aiming to develop design methods and criteria for the proposed high-performance frame.

A new type of assembly composite damping self‐centering brace is proposed to simplify the configuration, reduce the manufacturing cost, and improve its energy dissipation capacity, which is assembled by several modules in parallel with different functions. A brace specimen with a total length of 1.843 m was designed and numerically analyzed. The brace exhibits stable and full flag‐shaped hysteretic responses, and dissipates adequate energy during cyclic motion, with a high bearing capacity. When the brace is unloaded, the viscous damping force disappears, and the residual displacement can be basically eliminated. The hysteretic envelope area increases with the increase in loading frequency. When the frequency is 0.5 Hz and the target displacement is 30 mm, the activation force, ultimate bearing capacity, residual displacement, energy dissipation during one cycle, and equivalent viscous damping ratio are 622.5 kN, 1018.7 kN, 9.11 mm, 41.10 kJ, and 0.214, respectively. Under random loading, the damping force provided by the viscous module ensures a fuller hysteretic loop than the existing displacement‐type energy dissipation self‐centering brace. The influences of design parameters on the hysteretic performances of the brace were studied. When the disc spring stiffness increases from 3.27 to 9.80 kN/mm, the ultimate bearing capacity, residual displacement, and equivalent viscous damping ratio change by 18%, −24%, and −15%, respectively. The viscous damping coefficient and flow index of the viscous module should be increased, and the prepressed force and stiffness of disc springs in recentering module should also be appropriately increased.
