A comprehensive analysis and assessment system for structural monitoring of concrete
structures is under way within several projects of the collaborative research center CRC 477
“Structural Monitoring” at theTechnical University Braunschweig, Germany. Main components of
the system are a reliability-based system assessment tool, prognostic models of degradation and new
sensoring techniques. The system assessment tool is based on the reliability method; its task is to
find outweak points of a structure being first responsible for a possible failure. If prognostic models
of degradation are combined with monitoring an improved accuracy of prognosis can be achieved.
To get relevant monitoring data from a structure a new generation of sensors is being developed.
These three parts of a structural monitoring system are presented in the contribution.
