Comparative Analysis Concerning the Dynamic Response of Some Footbridge Structures with Steel Main Girders

摘要

In this paper some aspects regarding the dynamic behavior of the footbridge structures under the traffic actions correlated with the people comfort are presented. The comfort criterion during footbridge passing depends of the frequencies and accelerations of the structure which have to be situated between certain limits. In the paper are analyzed four footbridges from the point of view of the dynamic parameters and their influence of the resonance risk and of the traffic comfort.
