The Reliability Verification and the Actual Dynamic Behavior Assessment of an Existing Footbridge
Original language description
The dynamic experimental and theoretical analysis that is described in this paper was focused to the footbridge across Vltava River in Prague which was built in 1984. The footbridge was evidently sensitive to dynamic excitation by passing pedestrians since its putting into operation. Moreover during its existence the substantial part of the footbridge was overflowed by two great floods in August 2002 and June 2013 and an evident damage on the deck was found by a visual inspection after the second flood. At first the experimental modal analysis was performed. Secondly the dynamic load test focused to the footbridge vibrations caused by different groups of pedestrians was carried out. It was found out the deck vertical vibrations exceed the pedestrian comfort limit in some situations. Based on comparison of evaluated modes of natural vibrations with the appropriate ones from previous experiments, it was confirmed that the detected damage caused the partial variation of dynamic footbridge behavior.
