Design and Performance Evaluation of the Curved Hengjiang Avenue Pedestrian Bridge: Y-shaped Piers and Mixed Decks

Abstract

Urban pedestrian bridges should contribute to the improvement of the overall image and function of the place where the footbridge is located. In order to establish a complete pedestrian access area of a Green Belt Park, an elegant pedestrian landscape bridge with Y-shaped piers and mixed decks was designed and built, providing an open and diverse viewing experience. Accelerated bridge construction technologies were adopted to build the footbridge. Finite-element models, including the full bridge model and local model, were established and a continuous rigid frame and continuous girder composite bridge system was proposed after scheme comparison. Preliminary statics and dynamics analysis, as well as detailed calculations for the local stresses of Y-shaped piers and the shear lag effect of the deck, were carried out aiming to demonstrate its safety and suitability.
