Field measurement-based pedestrian-induced vibration analysis and comfort evaluation of a steel truss footbridge


Abstract:
We carried out a field measurement on the pedestrian-induced vibration of a steel truss footbridge connecting two buildings with a curved planar shape and a net span up to 45 m. Based on the Hilbert-Huang transformation, we effectively identified the dynamic properties of the footbridge, i.e., natural frequencies and damping ratios. We established the finite element mode of the footbridge. The finite element analysis results agree well with those of the field measurements. We also accessed the vibration serviceability of the footbridge using the domestic and international standards currently available.
