Report is presented as a guide for the design of flexural structural members in buildings with unbonded tendons. Suggestions are presented for needed revisions and additions to the ACI 318 Building Code regarding this subject. Consideration is given to determination of fire endurance, design for seismic forces, and catastrophic loadings, in addition to design for gravity and lateral loads. Recommendations are presented concerning details and properties of tendons, protection against corrosion, and construction procedures.
