A review of the current status and progress of steel arch bridges in China and Japan, as well as an outline of the design vehicle load and design method against global buckling for such bridges, is presented in this paper. The existing steel arch bridges in China and Japan were analyzed in terms of year of completion, main span length, structure type, main arch rib form and construction method. It is shown that the steel arch bridge in China has developed rapidly since 2000, characterized by a long main span, while in Japan it has stepped into a fast-growing period since 1955, with medium and small bridges holding a great majority. As for the main span length, most of the bridges have a span from 100m to 250m in China, while majority of bridges are shorter than 150m in Japan. Over 80% of the bridges in China are through and half-through bridge types, and the arch ribs are hingeless structures. However, over 88% of bridges in Japan are deck and through bridge types, and a two-hinged structure was mostly adopted in through and half-through bridges. Single-hinged and three-hinged arches were seldom adopted in the two countries. The rise-to-span ratios of the arches in China and Japan are mainly in the range of 1:6-1:4 and 1:7-1:5, respectively. Most of the arches both in China and Japan use solid box ribs, and only a small fraction uses truss ribs, in which box sections are mostly adopted for the truss members. The cantilever method and scaffolding method are the two main construction methods used in China and Japan, although some other construction methods have also been developed.
