ABSTRACT
Due to the excellent performance, aesthetic appeal, and economic advantages of cable-stayed bridges, they have become one of the most competitive bridge types for long-span bridges (Tang 1994). Many cable-stayed bridges have been built around the world in the past 60 years. There are three cable-stayed bridges with main spans longer than 1000 m (3280.8 ft.). The Sutong Bridge in China with a main span of 1088 m (3569.6 ft.), completed in 2008, is the longest cable-stayed bridge in the world (Zhang and Chen 2010). The Stonecutters Bridge in Hong Kong with 1018 m (3339.9 ft.) main span opened to traffic in 2009. The Eastern Bosphorus Strait Bridge with a cable-stayed main span of 1104 m (3622.0 ft.) opened to traffic in mid-2012. With the advent of high-strength materials for use in cables and the development of digital computers for structural analysis as well as of cantilever construction method, a great progress has been made in cable-stayed bridges (Walther et al. 1996). More cable-stayed bridges with larger spans are now in planning.
