Dynamic Response Analysis of Footbridges on Hot-Rolled Steel Girders for Spans Varying Between 10 to 40 m and Width Between 2 and 6 m
摘要
The dynamic behavior of footbridges with the structure made of steel hot rolled profiles, for varying spans and widths is investigated in terms of the resonance risk. The cross-section considered for the footbridge is one of the simplest and easier to implement when a pedestrian crossing is needed, therefore one of the most used. The calculations were done for varying traffic classes. The steel hot-rolled profiles used for the girders are IPE, HE, HD and HL profiles, chosen after the verification of each of the structures at ULS and SLS. A total number of 1344 were analyzed from the resonance risk perspective.
