| Outline of Final Research Achievements |
Prestressed reinforced concrete (PRC) interior beam-column-slab subassemblage specimens with transverse beams were tested under cyclic load reversals to evaluate deformation capacity of a PRC frame during earthquake excitation focusing on different limit states. Deformation capacity at peak flexural strength for a PRC beam were also researched based on recent proposal. Effect of both a contribution ratio of post-tensioning tendons to beam ultimate bending capacity and bond condition along PC tendons around concrete on structural behavior of a T-shaped beam in a PRC frame was indicated quantitatively by laboratory tests. The accuracy of beam deformation capacity estimated by the recent proposal at peak flexural strength was inferior. Additional deformation caused by pull-out of beam longitudinal bars and PC tendons from a beam-column joint should be considered in an explicit way.
