Dynamic properties of lively footbridge

The paper presents the concept of dynamic design of lively footbridge. The goal is to reduce dynamic excitation by tuning the structure. Tuning is based on local changes of stiffness, mass distribution or type of cables. This can be an effective way to change dynamic properties and exclude artificial dumping. Finally dynamic tuning can be attractive alternative to TMD devices. Tuning was implemented to practise. Two built footbridges are described in the paper. Three other theoretic examples are also presented. Theoretic base, methodology, discussion of results and final conclusions are presented.
