Theoretical predictive models of interaction between varying and moving loads and bridges for structural health monitoring

Ing. Shota Urushadze Ph.D.

The following proposal for the joint research project will be focused on the theoretical development and experimental verifications for structural health monitoring of bridge structures using indirect method by a moving instrumented vehicle and the combination with the wind load.  The project is focused on new methods of diagnostics, monitoring and identification, which determine the loading capacity and service life of structures with the use of dynamic response.  These procedures are based on the knowledge of load and response of the structures, course of fatigue and degradation of structure. The presumption is the application of diagnostics and simulation methods and measurement on real structures. The development of prediction methodology of the properties of further degradation and residual service life of structures is planned.

The solution of the problem will combine the experimental research on the real structures and the models carried out in the laboratory and wind tunnel. All applied loads will be determined based on traffic and wind loads for bridge structures.
