Biomechanically Inspired Modeling of Pedestrian-Induced Vertical Self-Excited Forces

摘要: AbstractAlthough many models of pedestrian dynamic loading have been proposed, possible bidirectional interactions between the walker and excited structure are generally ignored, particularly for vertical vibrations. This shortcoming has arisen from scarcity data on gait-adaptation strategies used in presence structural motion and, as a consequence, absence credible fundamental model capable capturing underlying relations two systems. To address this inadequacy current approaches, biomechanically inspired inverted-pendulum applied to human-structure interaction problem. The behavior is studied when subjected supporting structure, particular, relation potential self-excited forces that can be generated. A mechanism identified by which timing footsteps altered subtly, giving net damping effect without necessarily...
