Abstract
The article presents a method for identifying and analyzing the selected dynamic characteristics of deformation of a bridge structure using fiberoptic Bragg sensors with an inclined lattice. This paper describes the basic principle of operation of sensors based on a fiber Bragg lattice. Vibration modes were also determined using time series analysis with a high sampling rate. With the help of appropriate mathematical models (filters) and spectral analysis, it was possible to identify and describe the oscillation frequencies of the structure, which were compared with the theoretical model described by the dynamic behavior of the bridge. This model has been tested on a car and pedestrian bridge. With the help of the developed mathematical and experimental model, data were processed, and vibration modes were determined during vibration of bridge structures.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
