Abstract

The paper investigated the vibration of a high-rise building under
earthquake excitation. A system which is combined an active device and Tuned
Mass Damper device (TMD), is designed to reduce the vibration of the building.
The control law of active device is proposed based on Linear-quadratic regulator
method (LQR). During the earthquakes excitation, the high-rise building will
vibrate with high amplitudes, especially in the top of building. The location of
the active device is also considered to analyzed the performance of the proposed
system in the vibration reduction of the building. In order to examine the
effectiveness of the system, the study analyzes the vibration of the high-rise
building under different earthquake cases. The numerical simulation results
show the good performance of the proposed system to restrain the vibration of
the building.
