Whilst footfall-induced vibrations on buildings or bridges are normally ignored in terms of structural integrity, footfall vibration can be a critical serviceability condition. This publication guides the structural engineer through the process for designing for vibration, and includes flowcharts for calculation procedures and a useful glossary. The publication covers a new method for evaluating the response of a single pedestrian walking on a flat surface, such as a floor slab or bridge deck. The method was developed by Arup, and has been calibrated and refined with verification measurements taken on completed structures over a period of ten years. It also includes worked examples on a concrete footbridge, a low frequency multispan post tensioned concrete floor and a high frequency ribbed slab.
