Nowadays, it is well-known that for the structural safety verification of footbridges, and for the comfort guarantee of its users, it is fundamental to consider the effect of human induced vibrations, particularly: vibrations due to pedestrian traffic should be within acceptable limits for users; the lock-in phenomenon should be prevented; and, the footbridge structural safety should be guaranteed if subjected to intentional excitations. Recognizing a gap in lightweight footbridges design procedures, a guideline is presented in this document proposal for footbridges design taking into account human induced vibrations

Recognizing a gap in lightweight footbridges design procedures, a guideline is presented in this document proposal for footbridges design taking into account human induced vibrations
First, the proposed methodology is detailed. Attention is devoted also
to the response measurements, identification tests and instrumentation
used in the evaluation of the dynamic properties of footbridges. The
potential strategies to control the vibration response of footbridges
are reviewed. Finally, three worked examples of application of the
proposed design methodology are exposed, namely a simply supported beam
and two existing footbridges
