Seismic Vibration Control of Structures Using Superelastic Shape Memory Alloys

Structural vibration control has been approved effective design strategy for enhancing structural performance against earthquake and mitigating seismic response. Passive vibration control is a promising technology which has been widely used in earthquake engineering due to its simple configuration, low cost, easy maintenance and reliable run without power support. However, current technologies present some limitations, such as problems related to aging and durability, residual displacement, substitution after strong events, among others. Recently, the increasing research and development of smart materials and controlling devices open up a new area for seismic vibration control of structural engineering, providing a basic platform for the design and exploration of new generation high-performance structural systems.
