Civil engineering applications of smart damping technology
The worldwide escalation of the frequency and severity of natural disasters has exerted a heavy toll on human lives, buildings and infrastructures, regional economics, and socio-political systems. This alarming trend is the result of the increasing concentration of populations in regions that are pronr to high seismic activity, as well as other natural disasters ranging from hurricanes/typhoons to torrential rains and landslides. With many of the largest cities in Pacific Rim vulnerable, the trend toward larger disasters and increased human and financial losses is likely to continue. Supplemental damping strategies offer attractive means to mitigate this significant societal risk. In recent years, considerable attention has been paid to research and development of structural control devices with particular emphasis on alleviation of wind and seismic response of buildings and bridges. In both areas, serious efforts have been undertaken to develop the structural control concept into workable technology. Yet the engineering community has been reluctant to fully embrace this technology. Demonstrated cost-effectiveness and reliability are key considerations for acceptance and successful implementation of structural control. Because of their mechanical simplicity, low power requirements, and large force capacity, smart dampers provide an attractive alternative to active and hybrid control systems for structural vibration reduction. The focus of this paper will be to review two smart damping approaches that have been proposed and implemented in full-scale structures.
