vtechworks.lib.vt.edupurpose of the normal mild reinforcement is the control and distribution of cracking. Because of the high prestressing force, less conventional reinforcement is needed in the concrete, and members can be thinner and lighter, leading to more economical structures. The reduced susceptibility to cracking gives prestressed concrete higher durability.
