Pedestrian Induced Structural Vibration and the Walking Force Models Basing On Biomechanics: a Literature Review

Abstract

The interactions of structure-hum an and those of human-human would change the macroscopic behavior of human walking on the structure and which, would further result the change of walking forces. The complexity of walking forces during the interaction process is the reason that lively structures exhibit some special vibration behaviors under the crowd excitation. The walking forces observed through the traditional indoor footfall experiments can't fully reflect the interaction process. However, a biomechanics based walking force models can establish the relationships between human macroscopic activities and walking forces so that it can server as an alternative method. The biomechanical models describing human body dynamics and walking forces are reviewed and the problems to be studied in the field are suggested from the views point of human-human interaction and human-structure interaction.
