Abstract

A fiber Bragg grating accelerometer was developed for building and civil infrastructures. The accelerometer has a high sensitivity in low frequency range to cover the most important spectrum components of the structural response. The mechanism employed for the accelerometer ensures uniform strain distribution in the Bragg grating element so that the Bragg reflection peak will not be deteriorated. A shake table test was conducted to show good performance of a prototype accelerometer. The lifetime of the accelerometer was also probabilistically evaluated.
