Abstract

Vibration serviceability is a widely recognized design criterion for assembly-type structures likely subjected to rhythmic human-induced excitation. Current design guidance is based on the natural frequency of the structure. However, a phenomenon known as human-structure interaction suggests that there is a dynamic interaction between the structure and the occupants, altering the natural frequency of the system. It is unknown if this shift in natural frequency is significant enough to warrant consideration in the design process. Therefore, there is a need to identify the circumstances under which human-structure interaction should be considered because of its potential impact on serviceability assessment. Because the influence of the structural properties on human-structure interaction cannot be separated from the influence of the crowd characteristics, this study explores the interface of both factors through experimental testing. To do so, a laboratory test structure is designed, constructed, and operated based on particular design criteria selected with knowledge from previous human-structure interaction studies. This study provides a review of the design and construction of the test structure, methods used to validate a finite element computer model to the as-built structure, and the experimental testing procedure for testing with occupants.
