The system is based on the fibre Bragg grating (FBG) sensors or sensors using the optical time domain reflectometry (OTDR) technology. The essence of the solution is to introduce FBG sensors into the structure to make them act as its “nervous system”. The system may be implemented in existing civil engineering structures made of steel, concrete, reinforced concrete, as well as in shells and new structures at the design stage. The paper presents an example of an actual system operating based on FBG sensors and analysing the safety of Poland's longest steel footbridge. The footbridge is 35 years old. Periodic inspections of the Technical Inspection Office allow the footbridge operation if the structure meets the requirements stipulated by relevant regulations, but the decision is not based on a continuous analysis of the footbridge safety. The applied monitoring system makes it possible to analyse the footbridge operational safety on a continuous basis. The system informs about hazards, overloads, vandalizing acts, etc., and points to the need to take appropriate measures including the footbridge shutdown. The information concerning the state of safety may be sent on-line to any corner of the globe.
