Statistical, Probabilistic and Decision Analysis Aspects Related to the Efficient Use of Structural Monitoring Systems

Abstract

Structural reliability assessment as well as lifetime planning of engineering structures can be significantly improved by efficient design and use of monitoring systems. The design, selection, and placement of monitoring systems and their associated sensors are complex processes and need knowledge about the mechanical characteristics and performance of structures and monitoring systems. Since uncertainties are unavoidable in the design and planning of engineering systems, statistical and probabilistic methods are necessary for (a) the design of a monitoring system, (b) the determination of the necessary number of sensors, (c) the prediction of monitored physical quantities, and (d) the selection among monitoring alternatives. The objective of this paper is to discuss statistical, probabilistic, and decision analysis aspects that allow an effective use of monitoring systems.
