Abstract

In this paper, hysteretic performance of a new type of isolator called shape memory alloy spring-friction bearing (SFB) is studied both experimentally and theoretically. First, large scale superelastic NiTi SMA helical springs used for the SFB are developed. Then, the SFB specimen is designed and fabricated. Next, the quasi-static tests on the SFB under different loading conditions are conducted to study the influence of vertical pressure, displacement amplitude and loading frequency on the hysteretic curves and the mechanical parameters, such as the equivalent stiffness, the energy dissipation per cycle, the equivalent damping ratio and the equivalent kinetic friction coefficient. Finally, combining the restoring force model of SMA spring and the model of friction force, a simplified restoring force model of the SFB is established, which is employed to simulate hysteretic behavior of the proposed isolation device. The results show that the SFB exhibits unique restoring force-displacement curves and provides full hysteretic curves, excellent energy dissipation capacity and moderate re-centering feature. Moreover, the numerical results match closely with the experimental data, proving the validity of the restoring force model of the SFB.
