Abstract

Two fiber-optical methods for monitoring of stress processes in building structures under deformation are proposed. First method is based on using single-fiber double-mode interferometer as a sensor. It is shown that the single- fiber double-mode interferometer implanted into structure of a tested concrete unit allows to measure the unit structural deflection, absolute elongation and residual deformations in real time with accuracy not worse than 0.05 micrometers . It is also shown that the developed interferometric method allows to indicate a point of time of unit's crack initiation and also to estimate the crack opening displacement. Second method based on using single-fiber multimode as a sensor and photorefractive crystal allows to long-term monitor for dynamics of crack generation in real time.
