two horizontal dumbbells were used for each rib. Other configurations have single tubes further apart or a tight cluster of tubes known as “multiple contiguous”. Once hardened, the concrete solidifies and stiffens the arch, improving the compressive strength of the entire structure. The Yesanhe...
Hejiang is another of China's CFST or concrete filled tubular arch bridges in which the thin walled steel tubes sections are light and easily erected before concrete is pumped into them. Once hardened, the concrete solidifies and stiffens the arch, improving the compressive strength of the en...
Compressive strength of resource economic concrete : Evaluation of competition in highest compressive strength of resource economic concreteJohannes Bashar BasmahjiStefan Texén
concrete was pumped inside of them from the foundations upward to the crown. First used by the Chinese in 1990, they have refined and improved the technique and now use it on the majority of their steel arch bridges. Depending on the length of the span and the width of...
Once hardened, the concrete solidifies and stiffens the arch, improving the compressive strength of the entire structure. The north-south crossing is one of the highest bridges along the G76 Expressway between Bijie and Liupanshui in Guizhou Province. The main arch of 360 meters has a span...
with two tubes closely connected, a mix of a dumbbell and single tubes such as was done on the Beipanjiang River Railway bridge or a tight cluster of tubes known as “multiple contiguous”. Once hardened, the concrete solidifies and stiffens the arch, improving the compressive strength of...
