Bottom formwork of large-span arch bridge

Bottom formwork of large-span arch bridge

This is another project we adopted steel-concrete structure. What is the maximum span of corrugated steel structure can achieve to be? If its span is more than 20m, we have to consider other reinforcement method.

This is another project we adopted steel-concrete structure. What is the maximum span of corrugated steel structure can achieve to be? If its span is more than 20m, we have to consider other reinforcement method.


As the picture show, this arch span is more than 20m,for safety consider, we decide to adopt the steel-concrete structure to meet its strength request.


On the outside of the corrugated steel structure, we woven steel cages and use steel plate to be model plate to inject concrete in the steel cages.


Then it has one layer of steel corrugated steel shell and one layer of concrete shell, it is much strong than only corrugated steel structure.
