Why does the prestressed losses in post-tension concrete members are less than pretension concrete members?
Dear Anand, you focused on the friction losses that occurs in post-tension members only ofcourse. This should make the losses in post-tension greater than pretension prestressed members while in fact it's not!
In construction material engineering aspects, does concrete considered a heterogeneous or homogeneous mixture?
