ViCo: Structural Seismic Vibration Control (2006-2017)
Advances in structural engineering design have addressed the limitation of the buildings’ inherent ability to dissipate seismic energy, as cost rises exponentially with the vibration requirements. Therefore, earthquake damping technologies have been introduced as a means to mitigate ground motion effect on structural response. This alternative is cost effective and more flexible in terms of re-configuration, as the urban environments advance toward smart cities, as interconnected systems of systems that are both complex and large scale.
During this project several studies were performed, including control systems for base isolation, electrohydraulic and magnetorheological dampers, etc. with the purpose of reducing the vibrations of structures during earthquakes. Please see publications for more details.
