Externally Bonded FRP Composite and Viscoelastic Materials for Mitigating Vibrations of Floor Systems

Floor system vibration control may be achieved using passive, semi-active, and active systems. Typical passive dampers include tuned mass dampers (TMDs). A semi-active damper can be produced by making one of the parameters of a passive damper active such as controlling the variable tuning of a TMD with computer and instrumentation system. Fully active systems make use of sensors and actuators controlled by a computer system to produce forces that counteract externally applied forces (Breukelman and Haskett, 2001).
