The continuing decline in traditional manufacturing industries and a trend towards a more high-tech and service-based economy in the UK have created an unprecedented demand for high-quality open-plan space in multi-storey buildings to accommodate high-tech manufacturing and offices. To satisfy this need, long-span steel and/or concrete composite flooring solutions have regained their popularity to such an extent that their annual market value is estimated at more than 1 billion to the UK building construction industry. The vibration response of long-span composite flooring systems is frequently the governing design criterion, particularly when pre-cast concrete elements with little or no in-situ concrete topping are used to simplify and speed up the construction. The two currently available design guidelines published by the Steel Construction Institute (SCI) and the Concrete Society, neither of which were experimentally verified before publication, have proved to be inadequate and are often over-conservative. This increases the cost and reduces the effectiveness of most long-span building floor solutions.The aim of the project is to provide tools to remedy this by employing advanced dynamic testing (multi-shaker excitation) and analysis (FE model updating) technologies. It is expected that more reliable estimates of damping and distribution of the floor stiffness will be obtained by multi-shaker modal testing. This will be verified by employing FE model updating technology that will render more reliable analytical models. Finally, these updated models will be validated against an extensive set of experimental response measurements leading to a better understanding of the problem and much improved design guidelines.
