Abstract
For large-span flexible structures, human-structure interaction is obvious, but designers do not have a clear understanding of whether human-structure interaction should be considered in structural design. In this paper, the pedestrian Spring-Mass-Damper (SMD) model and dynamic parameters are used to study the influence of human-structure interaction on structural dynamic properties by using ANSYS finite element calculation software to calculate and compare 70 working conditions. The results show that when the structure-human frequency ratio is less than 1 and slightly greater than 1, the human-structure interaction has a greater influence on the dynamic properties of the structure. As the structure-human frequency ratio increases, the influence of the human-structure interaction on the dynamic properties of the structure decreases. When the structure-human frequency ratio is greater than 2, the human-structure interaction can be ignored.
