Abstract

The characterization of traffic effects on a short span railway bridge in Northern Portugal with a new hybrid platform that allows the simultaneous assessment of signals generated by a sensing network composed of both electrical and fibre Bragg grating based sensors was demonstrated. A Bridge Weight-in-Motion algorithm was also developed, which allows on-motion determination of train speed and weight distribution with only three fibre Bragg grating sensors.
