A method for verifying the results of virtual modeling of building structures using fiber-optic technologies

This article presents the results of a comparative analysis of isofields and isolines of the distribution of the main tensile stresses, indicating the orientation of the elementary areas of their application in a bendable reinforced concrete slab, obtained using the SCAD Office software package, with the results of an experimental research using fiber-optic sensors based on fiber Bragg gratings (fiber Bragg grating - FBG). The results of modeling and experimental research were obtained with a balanced loading of the slab over the entire surface with free support along the perimeter. A model made of organic glass with isotropic elastic characteristics was considered as the tested sample. The article shows the fabricated experimental setup and presents the results of a survey of sixteen fiber-optic sensors placed on the internal and external surfaces of the tested sample.
