Abstract
Modal analysis is commonly considered as an effective tool to obtain the inherent characteristics of structures including natural frequency, modal damping and mode shapes, which are significant indicators for monitoring the health status of engineering structures. In this paper, distributed fiber optics, as dense measurement transducer has been applied into acquiring huge amount of strain data along the beam surface. Thanks to the dense spatial resolution, CMIF (Complex Mode Indicator Function) is used to identify strain modal parameters like natural frequency and modal damping. Strain mode shapes can be obtained by using SVD technique. © 2016, IMEKO-International Measurement Federation Secretariat. All rights reserved.
