Probabilistic model updating of controller models for groups of people in a standing position

Abstract

The effects of occupants over the dynamic properties of a structure have been traditionally modeled showing the human body as lumped masses connected with spring and dampers. A new approach for modeling the effects of a standing person was developed 2 years ago based on control theory. The new approach starts from the assumption that the human body can input energy into the system, changing the response of the structural system. The control theory based models have shown to work for a single occupant. This work presents the modeling of groups of standing people using a controller model. The parameters of the controller are obtained using a probabilistic approach based on Bayesian model updating.
