Abstract
Monitoring deformations of structures or testing of supporting elements are important activities in life cycle of structures. Determined large deformation may indicate defect or failure of supporting structures. The aim of the experiments is to show another, less frequently used strain measurement method. The fibber Bragg grating sensor was used for measuring of the strain changes in simple supported concrete beam. These sensors based on optical fibers allow to measure the strain of the fiber by changing the wavelength of light in the deformed fiber. The article describes an experiment conducted at the Faculty of Civil engineering VŠB Technical University of Ostrava. The values measured by these sensors are compared with measurements using traditional methods.
