DESIGN CRITERIA AND ANALYSIS FOR DYNAMIC LOADING OF FOOTBRIDGES

WebIn specifying the magnitude of the dynamic load to be used in design rules it was decided that the more sensitive existing footbridges should be considered just acceptable. This led to a dynamic load equivalent to one pedestrian. Abnormal loading by a group of vandals deliberately exciting a footbridge at its natural frequency was considered. WebMay 12, 2016 · The degree to which the dynamic behaviour is modified, is expected to increase with an increasing ratio of the crowd’s mass to the structural mass. Hence, for lightweight footbridges these effects are expected to be non-negligible [14, 15]. This paper proposes a crowd-structure model that accounts for pedestrian excitation and HSI. cablecard tuner hdmi
