Abstract: | This paper introduces the state-of-the-art of longspan bridge engineering in China with emphases on recent long-span bridge
projects, bridge deck configuration and material, design codes of long-span bridges and improvement of aerodynamic performance.
The recent long-span bridge projects include thirty-eight completed suspension bridges, cable-stayed and arch bridges with
a main span over 400 m, and eighteen major bridges are under construction. The bridge deck configuration and material, with
prestressed concrete decks, steel-concrete composite decks and steel box decks together with several popular cross-sections,
are presented. The third part briefly outlines four design codes, including static and dynamic design for highway long-span
bridges, and the recent engineering experiences gained from several aerodynamic vibration control projects of long-span bridges
are shared in the last part. |
