Abstract:
This report is presented as a guide to the design of structural members in buildings prestressed with unbonded tendons. Design with bonded tendons is covered in detail in ACI 318-63; only limited provisions are set out there for unbonded tendon design. The following additional provisions are recommended to supplement existing design provisions for unbonded tendons. Consideration is given to the design of members and to the details and properties of the tendons, their anchorages and methods of protecting them from corrosion. Prestressed ties have been excluded from these recommendations although portions of these recommendations may be applicable.
