摘要: Structural damage identification is a coral and challenging research topic. Research mainly focuses on detection of linear in structures by using modal parameters such as change natural frequency, frequency response function, mode shape, etc. Transmissibility conventionally defined the spectra ratio two measurement points, which has been utilized for powerful indicator. In this paper, strain transmissibility, spectra, proposed new order to achieve more precise sensing information, distributed fiber optics applied beam structure, adds capability with its combination high spatial density dynamic acquisition over single optical sensor. A numerical simulation conducted investigate feasibility transmissibility revealed better performance compared traditional transmissibility. The applicability method confirmed applying clamped-clamped beam. Both experiment validate effectiveness approach based optics.
