| Outline of Final Research Achievements |
Loading tests of reinforced concrete columns and multi-layered beams, and pull out tests of tension reinforcing bars, were carried out. An influence of bond and axial force on the capacity of the member was investigated. Especially, the influence of multi-layered longitudinal bars and cut-off bars was discussed. The shear capacity formula for members failed in shear and bond splitting was improved to be applied to members with multi-layered longitudinal bars including cut-off bars. In addition, inclusive evaluation method to design the flexural members of sufficient performance was proposed; which were consideration of axial force and strain rate, checking method for bond around cut-off bars, and evaluation method of deformation capacity after flexural yielding.
