Numerical analysis of FRP pedestrian bridge in Taijiang National Park

In this paper, the numerical analysis of the pedestrian bridge made of glass fiber reinforced plastic (GFRP) components in Taijiang National Park, Tainan, Taiwan was introduced. The bridge's superstructure used 4 GFRP I-girders which are connected to each other with GFRP plate decks and GFRP stiffeners were used to resist shear while also helping transmit forces to adjacent girders. This study aims to analyze the bridge superstructure by modeling it using ANSYS in the finite-element analysis. Also, small scale analysis of a 6-m long and an 8-m long girder were performed. The finite-element results were compared with the Euler and Timoshenko beam theoretical values.
