To achieve a cost-effective, rational, and efficient structural system, two traditional structural systems—a continuous rigid frame (CRF) girder bridge and a deck arch bridge—are combined to form a new bridge type—arch-stiffened girder (ASG) bridge. This bridge type fulfil the innovative and unique requirements for the Chongqing Lijia Jialing river bridge. The ASG bridge combines the simplicity of a girder bridge with the elegance of an arch bridge. In terms of structural behaviours, the ASG bridge utilizes the arch to assist the main girder and forms a self-balancing system, significantly reducing the mid-span and side-span girder lengths, and thus optimizing structural performance through increased vertical stiffness and effective control of long-term deflection. This article discusses the major components of the Chongqing Lijia Jialing river bridge's design, construction, load capacity testing, and effects upon completion. |
