Abstract

Stay cables in cable-stayed bridges experience vibrations due to wind, rain, and traffic-induced excitations and may suffer fatigue damage. Shape memory alloy (SMA) material can protect cable damages from fatigue issues. This paper summarizes the applications and effectiveness of SMAs for mitigating cable vibration. SMA wires have greatly enhanced the performance of cable structures because of its super-elasticity and shape memory effect. SMA wire hysteresis behavior is analyzed on Mechanical ANSYS Parametric Design Language in order to obtain the stress–strain response. Because of the above properties, shape memory alloy wires exhibit large hysteresis loops under cyclic loadings with negligible or no residual strains. The effect of temperature under the influence of loading was also studied. The ambient temperature has its marked effect on the superelasticity and shape memory behaviors. It is concluded that the passive dampers made of the shape memory alloy Ni–Ti wire quashes the stay cable vibration effectively. It is expected that the information collected in this paper would serve as a repository of information for SMA damper. An artistic view of a SMA damper has been presented. The future research would focus to develop an improved SMA-based damper, which may be effective in quashing the vibration effects developed by wind or earthquake.
