Research review of the mechanical properties of corrugated sheet steel-concrete composite bridge decks
The applications in the actual engineering and research status of corrugated sheet steel-concrete composite bridge decks are introduced.Research results show that:(1)Compared with concrete bridge decks,the new composite bridge deck has light weight,while has a higher bending capacity and rigidity.Compared with steel bridge decks,the new composite bridge deck has more excellent anti-fatigue resistance.Based on the above advantages,the new composite bridge deck has a broad application prospect.(2)At present,the research on the corrugated sheet steel-normal concrete composite bridge deck mainly focuses on the static property,and more theoretical and experimental studies on its fatigue property are needed.There are little research on the corrugated sheet steel-ultra-high performance concrete composite bridge deck,and more researches on its static and fatigue properties are needed.(3)Adopting the ultra-high performance concrete,selecting the shear connector type reasonably,reducing the number of welds on the premise of ensuring the reliable connection between corrugated sheet steel and concrete,and improving its fatigue resistance are the developing direction of this new composite bridge decks.
