Abstract
With the aim of reducing the carbon footprint of the construction industry, three pedestrian bridges, are
currently being developed as Smart Circular Bridges (SCB). The bridges innovate through the use of a novel
bio-composite material and by incorporating Structural Health Monitoring (SHM) technology, consisting of
accelerometers and embedded optical strain sensors. This paper discusses the SHM setup and gives initial
results from the first installed SCB. Analysis from a controlled test, consisting of an experimental modal
analysis when the bridge was still in the factory, is compared to results found from a field test during the
first months of operational use. Here, the acceleration data is processed using automated operational modal
analysis. The effect of environmental variables on tracked frequencies and a strategy for simplifying datanormalization of the dynamic properties are detailed. Finally, alternative machine learning strategies could
be used to detect anomalies in the spectrum or detect events occurring on the bridge from SHM data only.
