Abstract

The monitoring of building structures deformations and testing of construction materials resilience are very important processes in the development and production of given materials and structures. This paper deals with the concrete deflection measurement using fiber optic distributed strain system. The own principle of the measurement evaluation is based on stimulated Brillouin scattering. In this paper, we explore the use of different types of optical fibers and the possibilities of their fixing. Above all, we are focusing on the possibility of their attachment to the measured objects. This is the most important step of the whole process that most affects the functionality and accuracy of measurement.
