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.
WebDec 18, 2024 · Dynamic models of pedestrian loads. Two separate dynamic models of pedestrian loads for the design of footbridges could be defined: a concentrated force (F n), representing the excitation by a … WebRecognizing a gap in lightweight footbridges design procedures, a guideline is presented in this document proposal for footbridges design taking into account human induced vibrations.
