Abstract

This review paper discusses the potentials and applicability of cheaply processed Cu and Fe based shape memory alloys for vibration control in civil structures. Evidences available show that most devastations from seismic activities are accentuated by the consequent tremor induced collapse of buildings and civil structures. Accordingly, measures for controlling the threats of structural vibrations has been a huge concern globally. NiTi based shape memory alloys which possess excellent damping properties have been the focus in recent times for the design of vibration control systems. However, the prohibitive material costs and complexity of processing has raised concerns on the practicality of their commercial utilization in buildings and civil structures compared to other vibration control approaches. From this background, this review paper advances the use of Cu and Fe based SMAs by exploratory examination of the extent of their use in buildings and civil structures as vibration control devices/systems. Based on the findings from the literatures analyzed, it is concluded that Cu and Fe based SMAs are technically useful, simply implementable and sustainable SMAs for consideration as structural vibration control systems/devices in buildings and civil structures.
