Evaluation of static and dynamic characteristics of GFRP pedestrian girder bridge considering variation in material properties

Abstract

The purpose of this study is to elucidate the effect of variations in material properties of GFRP materials on the response performance of pedestrian bridges. First, the static loading test and the vibration test are performed on the actual GFRP pedestrian girder bridge assembled in the factory before completion, and the response performance of the bridge is evaluated. Then, the response analysis of the actual bridge was performed using the constructed finite element model. In addition, the performance of the bridge is statistically evaluated by conducting Monte Carlo simulation assuming the variation of material properties.
