| Outline of Final Research Achievements |
The evaluation formula for predicting the ultimate flexural strength and deflection of a beam in a precast prestressed concrete frame, which is assembled by post-tensioning unbonded tendons within ungrouted sheaths, called an unbonded PCaPC frame, was proposed in a simplified and explicit way based on a macro-model which was newly created. The adequacy of the formula was verified through results of the tests using beam-column subassemblages under lateral load reversals.
It was confirmed by the tests that an exterior beam-column joint in unbonded PCaPC frames also fails in a joint hinging mechanism as well as in reinforced concrete frames.
