Post tensioning is economical for large span and is adopted now a days.

Mohd Atif said:   1 decade ago
As it it economical for large span also it reduces dead load of structure thereby reduces stress.

What is meant by post tensioning?

Mohit said:   1 decade ago
A method of prestressing concrete by tensioning the tendons against hardened concrete.

Miss Rupali said:   1 decade ago
For post tensioning, while concreting any member ducts are provided intentionally through which the tendons are kept in tension will give to the member after hardening of concrete.

Post tensioning is how useful are economical?

Umamahesh.D said:   1 decade ago
Now a days prestressing by post tensioning method is most economical for large spans especially for bridges. Lesser the dead load more the resisting capacity.

Now a day Pre stress are not use.

It reduces self weight there by reducing bending moment and shear force, increase gap between moment of resistance and bending moment, the research is being carried out still on this process.

Yes we are use the prestress concrete for box girder in bridge.
