Long-term monitoring of strains in a real operation of structures

Vladimir Chmelko, Martin Garan
Abstract:
In most of cases the structural condition monitoring allows to receive significant states or values in a real operation of that structure, such as:
- change in value of safety coefficient by reason of arising overload or non-standard operation mode during service
- vibrations increasing by reason of change in toughness of the structure
- increasing of fatigue damage accumulation in a critical point or section by reason of change in variable stress amplitudes
In this paper, there is presented the extended concept of compensation for elimination of unwanted offset change that can appear during long-term monitoring of the strain signal. The method of this compensation is shown and realized for performing the monitoring process on a real structure of pipeline system where as sensors were used the strain gauges.
