Dynamic Identification of a Pedestrian Bridge using OMA: Previous and Post-Reinforcing

Abstract

Postiguet footbridge in Alicante is a very sensitive structure to vertical vibrations and it has been restored with fiber glass composite materials to improve the response to dynamic loads. This article describes the studies carried out on the walkway in the conditions prior and after to the intervention of structural restoring. This allowed identifying the characteristic parameters of the dynamic behavior of the footbridge. The values of the natural frequencies of vibration and the damping coefficients of the structure have been determined for the different modes of vibration in the two structural conditions. Operational Modal Analysis (OMA) techniques for the modal identification have been utilized and a numerical model has been built to clearly identify the vibration modes and to compare the results.
