Abstract: Vibration serviceability has become an important issue in the design of modern slender footbridges with
large spans. The natural frequencies of these bridges are often in the range of the loading frequencies of
the dynamic walking excitation of (groups of) pedestrians. This causes vibrations which may reduce the
comfort of the users of the footbridge. This paper presents the evaluation of the vibration serviceability of
a footbridge in Wetteren according to 3 recent design methodologies: Willford M.R. & Young P. (2006)
[1], the French guideline of Charles P. & Hoorpah W. (2006) [2] and the European guideline Hivoss
(2008) [3]. These design procedures are compared regarding the modeling and the assumptions made on
the following issues: the modeling of the human-induced loads, the characterization of the dynamic
behavior of the footbridge, the calculation of the vibration levels and the evaluation of these vibration
levels. The results illustrate the different approaches used in the design procedures leading to a different
evaluation of the vibration serviceability of the footbridge.
