Interaction between structures and their occupants

Abstract

Structures that carry humans are the subject of the studies of this paper. Active humans may cause structural vibrations, which can be problematic, but passive humans (sitting or standing on the structure) are also potentially present on the structure. In predictions of structural vibration performance, the passive humans are often not modelled, but they will interact with the structure. The paper has focus on the effect that the presence of passive humans has on the structural behaviour and modal characteristics of the structure. Based on findings from measurements, the implications of presence of passive humans are discussed.
