摘要: The suitability of the group load for vibration serviceability of footbridges in vertical direction is analysed. The rationale is that the more pedestrians are on a footbridge the more the actual effect of the presence of pedestrians as dynamic systems is relevant for the vibration response. Therefore, it is expected that, by increasing the number of pedestrians, representing pedestrians only as loads would diverge from reality. To investigate this matter, measured responses from controlled tests of crossings of single and of groups of …
