Structural identification for condition assessment of civil infrastructure

The experimental aspects of structural identification for global and local condition assessment of constructed facilities are summarized. Experimental techniques suitable for meaningful field testing have been explored on an operating reinforced concrete deck-on-steel stringer highway bridge which served as a test bed. Modal analysis and instrumented monitoring applications conducted on this bridge serve to exemplify the experimental steps of a possible global structural identification methodology for health monitoring of civil infrastructure. The results given indicate that this is a feasible approach to for condition assessment and structural health monitoring
