Abstract

A description is given of the developed fiber-optic system for monitoring structural loading (arch-bridge elements) operating in real time and warning of approaching the critical level of loading. The criteria for working capacity of the design of the a two-lane automobile arched bridge. The choice of the main criterion was made on the basis of the principle of assessing the structural stability of the structure taking into account the capabilities of the equipment used. It is shown that the relative axial deformation of the arched elements practically did not change over the period of observation.
