Nowadays more and more slender concrete footbridges are designed. Footbridges are designed thinner to increase esthetic value, as well as incorporate sustainability and to reduce building costs, with a consequence that the eigenfrequency of the bridge can drop so low that it may fall into a range of frequencies that is susceptible to vibrations...
