Dynamic Analysis of a Footbridge Structure on a Central Arch

Abstract

In this paper some aspects regarding the dynamic behavior of footbridge structures under traffic actions correlated with the people’s comfort are presented. The comfort criterion during footbridge passing depends of the frequencies and accelerations of the structure which must be situated between certain limits. If the frequencies and accelerations of the structure are in the critical domains, some measures to modify them must be taken.
