Abstract

Before and after the 1980s, the China built many reinforced concrete multi-rib arch bridges. With the increase of traffic volume and load, the carrying capacity of the multi-rib arch bridges are obviously lower, it is necessary to take various measures to strengthen and enhance bearing capacity of these bridges. This paper proposes a reinforcement method by adding cable towers in two ends abutment of arch bridges and the inclined cables to improve behavior of RC multi-rib arch bridge. The main idea is that additional bridge towers are set on two side abutments of the RC rib arch bridge with single span to hang stayed cables. Newly-casting RC longitudinal beams are set in two sides of the bridge and the transverse prestressed steel tendons with \( 4{\upvarphi }^{\text{j}} 15.24 \) steel strands on the both sides of every cross beam were stretched, which are wrapped by the steel tubes and connected with longitudinal beams, to enhance the integrality and stiffness of the multi-rib arch bridge. Then, the longitudinal beams of each side of arch bridge are supported by using stayed cables through the cable tower. Comparison of the values gained by space finite element and field test confirmed that the proposed method for strengthening the rib arch bridge and enhancing the bearing capacity is effective.
