T1 - Nondestructive evaluation and structural health monitoring N2 - The European project Smart Management of the Sustainable Human Environment (SmartEN) aims at developing and planning of early proactive measures to reduce the environmental impact of human actions, the influence of climate changes and to protect infrastructure as well as the environment. The work of SmartEN is organised in an initial training network (ITN) of early stage researchers (ESRs) in European universities, research Institutes and in industry. The participation of specialists from different disciplines as structural engineering, structural health monitoring, non-destructive testing, computational techniques and telecommunication allows a cross-themes Cooperation. The Cooperation between young engineers and scientists from different disciplines aims at improving the career perspectives of early stage researchers in both public and private sectors and enables them to create multidisciplinary networks in the field of structural monitoring. The project is structured into four thematic work Programmes: Wireless sensor networks, sensor signal processing, non-destructive evaluation and smart proactive management. Besides an in-depth theme about corrosion mapping with ground penetration radar (GPR) in work Programme 3, BAM is involved in specifying the links between NDE, inspection and SHM in structural engineering, including small and medium span bridges. The Work Programmes considers multidisciplinary tasks besides the PhDs that solve a specific open task in the defects detection. Multidisciplinary tasks to be considered in the field of NDE are the limitation and applicability of methods for the intended use for detection of the most critical parameter considering (1) Implementation of NDE in structural health monitoring, (2) Requirements on non-destructive evaluation, (3) Optimum sensor placement in infrastructure with special focus on small and medium span bridges and (4) Combined Monitoring and inspection Systems. In Smarten Work Programme 3, we studied the contribution of NDE to monitoring from a civil engineering point of view. An example presents NDE requirements from laboratory tests on demonstration specimens for ground penetration radar.

A1 - Günther, Tobias A1 - Wiggenhauser, Herbert T1 - Periodic mapping of reinforcement corrosion in intrusive chloride contaminated concrete with GPR N2 - This paper presents an experimental effort for developing a novel reinforcement corrosion monitoring technique based on Ground Penetrating Radar (GPR). Experiments were carried out to periodically monitor the accelerated reinforcement corrosion process with GPR. The data were processed in both time and time–frequency domains to investigate the tendencies of GPR signal attribute changes related with corrosion, moisture and chloride contamination. Data processing methods were proposed to visualize the reinforcement corrosion and chloride distribution with target specified signal attribute mapping. Half-Cell Potential (HCP) and Laser-Induced Breakdown Spectroscopy (LIBS) methods were employed to verify the GPR observations.
