Effect of the Length of Traffic Flow Records on the Estimate of a Bridge Service Life

Effect of the Length of Traffic Flow Records on the Estimate of a Bridge Service Life Abstract The service life of bridges is significantly affected by fatigue of used material induced by heavy vehicles. Therefore, precise determination of the vehicle weight is of crucial importance for the calculation of fatigue damage and the prediction of the bridge serviceability. This paper investigates accuracy of the determination of fatigue depending on the length of traffic flow recording. The presented data were obtained from the measurements carried out on a bridge of the Prague Highway Ring. The analysis reveals that the optimal length of traffic recording is about 30 days. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Transactions of the VŠB – Technical University of Ostrava, Civil Engineering Series. de Gruyter

Abstract

Abstract The service life of bridges is significantly affected by fatigue of used material induced by heavy vehicles. Therefore, precise determination of the vehicle weight is of crucial importance for the calculation of fatigue damage and the prediction of the bridge serviceability. This paper investigates accuracy of the determination of fatigue depending on the length of traffic flow recording. The presented data were obtained from the measurements carried out on a bridge of the Prague Highway Ring. The analysis reveals that the optimal length of traffic recording is about 30 days.
