Numeric Based Optimization of Monitoringsystems Applied on Arch Barriers

Monitoring of critical structural and process key parameters of concrete barrier structures and associated processes, during construction and operation, provides a quantitative basis for reliability and condition assessment, analytical modelling and decision making. This includes evaluating the conditions and induced effects during construction and operation in terms of maintenance decision making and reliability assessment Recorded Data can provide direct or derivable information of indigent or existing failure or failure zones, An optimized monitoring system with respect to the interaction and the location of sensors combined with probabilistic nonlinear numerical and analytical methods is a proper instrument essential supporting by such challenges. The objective of this paper is the discussion of a probabilistic based assessment method for barrier structures combining monitoring information, optimized by the presented strategy, and advanced nonlinear Finite Element Methods.
