Abstract

The liveliness of the floor system at the Imperial Centre due to vibration is well known. The magnitude of the
floor vibration is unknown and is caused by pedestrian activity. This raises questions about structural performance and serviceability for longevity and future use. This project assesses the serviceability of two supermarket floor systems by implementing a range of existing design procedures developed primarily for pedestrian activity on foot bridges. The validity of these procedures on supermarket floor systems is investigated. Erina Fair is not known to be lively and is used only for comparison. Determination of the dynamic behaviour of floor systems in service is quite complex. In this project, an actual measured response is obtained from the modal testing of two supermarket floor systems, whereas the numerical response is predicted using finite element modelling. The measured responses obtained from the Imperial Centre and
Erina Fair are compared to the predicted numerical responses obtained from the finite element modelling to validate the excitation models and propose a new model, and to assess the serviceability of the floor systems. Further work includes long term vibration monitoring for trends and loading patterns in supermarket floor systems to build upon
the suggested model.
