Wind tunnel investigation of active vibration control of tall buildings

An active tuned mass damper (ATMD) installed in the top of a rectangular model building was tested in a wind tunnel for its effectiveness in suppressing cross-wind building vibrations. The ATMD was controlled using a sub-optimal control algorithm. Certain parameters critical to the operation of the ATMD were varied to observe how the ATMD's effectiveness would be altered. The ATMD was found to be effective in reducing cross-wind vibrations. The vibration in design parameters of the ATMD resulted in different levels of reduction.
