Building Structure with Pendulum Neutralizer Vibration Analysis Using FBGs Strain Sensors

Abstract

In this paper, the response of the fiber Bragg gratings applied to vibration control of a prototype building structure is analysed. The dynamic vibration control is based on the pendulum neutralizer without damping. The primary and compound system responses were obtained using finite element method and experimentally. These analyses were performed without and with pendulum neutralizer. The tests results are in qualitative accordance with the theory. This study validates the effectiveness of the vibration measurements from the fiber Bragg gratings combined with vibrations control in low frequencies, encouraging future applications.
