Abstract

In the past 30 years, China’s concrete-filled steel tube (CFST) arch bridges have developed rapidly, and more than 450 CFST arch bridges have been built so far. With construction of the 1st Hejiang Yangtze River Bridge with 530 m main span, the construction of Hejiang Yangtze River Highway Bridge in Sichuan (span combination 80.5 + 507 + 80.5 m) and the 3rd Pingnan Bridge in Guangxi (main span 575 m), the span of CFST arch bridges has reached main span larger than 500 m.

In order to solve a series of technical problems of CFST arch bridges, Chinese scholars have carried out a number of theoretical studies and technical practices, and formed a series of technical achievements of long-span CFST arch bridges: new structural system of main arch has been developed, new technology of main arch using composite structure with full steel tube has been put forward, and independent unit system of main arch has been developed. New structures such as composite main arch transverse brace, rectangular arch rib inner diaphragm, wind-resistant and vibration-reducing series cables and long-term cable anticorrosive suspension system have been established. The unified theory and constitutive relationship of CFST capacity have been established. The non-linear stability analysis of long-span CFST arch bridge has been put forward. The series technical achievements have established a solid foundation for the development of large span CFST arch bridges and reinforced concrete arch bridges with rigid skeleton.
