Design Considerations for Arch Bridges

Chenab Bridge is being constructed over the Chenab River in the Himalayas. This arch-shaped steel bridge will become the world's highest railway bridge, with a total height of 359 m (1178 ft.) above the river, 35 m taller than the Eiffel Tower. It will connect Baramulla to Jammu.

The Centennial Bridge in the city of Oradea, Romania was commissioned by Oradea City Hall to a joint venture formed of FreyRom SA & Procons SA and was designed by Integrated Road Solutions SRL in 2017-2018. The bridge was built during 2018 and was opened to traffic on 1st of December 2018, to mark the 100 years since the country was united. The bridge is an arch having a span of approximately 80m and supports a two lanes carriageway and also 2 footways with a width of 3m each.

Arch Bridges are one of the oldest types of bridges and have great natural strength due to its geometry. Since the weight of arch bridges is carried outward along the curve, from the arch to the supports, they can be the perfect choice for long-span erections. Many new developments and improvisations on the design and construction of arch bridges have taken place in recent years, one such is the utilization of Concrete-Filled Steel Tubular (CFST) structures to arch bridges. This article will mainly focus on the use of CFST structures in arch bridges and some examples of CFST arch bridges in China.
