ABSTRACT
ABSTRACT This paper presents a method for the characterization of the fatigue failure of fastening systems in combination with a coordinated health monitoring concept. The required hysteresis model is based on an approximation of the hysteresis loops using measurement data and forms conformance criteria. The developed predictive model uses four adjustment parameters (determined through regression analysis), was applied to experimental fatigue experiments of anchor channels in concrete. Additional investigations of the adjustment parameters indicated the potential to identify an indicator for forecasting the experimental data at an early stage, in relation to specific changes in the shape and area of hysteresis loops. Furthermore, the determination of the centroid - being a sensitive characteristic of the loop geometry, is achieved through numerical methods on the basis of measurement data. In a subsequent step, the method is applied to a health monitoring concept with appropriate measurement technology and discussed.
