EN Designing of light footbridges, sometimes with an innovative and complicated form, it is now quite popular. The relatively low weight of the superstructure and its small stiffness adversely affect the dynamic behaviour. Even the proper design and execution of the footbridge structure, in accordance with current standards does not provide a sufficient guarantee of non-occurrence of excessive vibration due to the random nature of the impact of pedestrians or wind. In this paper the recommendations of the dynamic analysis of footbridges contained in PN-EN 1991, EN 1991-2, EN 1991-1-4, PN-EN 1995-2 and basic standard PN-EN 1990 with current patches and existing national attachments are presented. The main purpose of this article is synthesis and analysis of computational methods in dynamics on footbridges and some proposal for algorithm of dynamic design.
