| Outline of Final Research Achievements |
In this research, RC columns with one sided wing wall, which exhibits excellent properties in ductility and damage tolerance, were developed. The idea to reduce the damage and enhance the deformation are as follows. ① PVA fiber reinforced concrete is used as an alternate material of a conventional common concrete. ② It is to restrain the concrete in compressive zone of wing wall with high strength circular spiral reinforcement. The range is also zone of over 2.5t (t = thickness of wing wall) from the capital section and column base section.
A total of 6 specimens were tested to demonstrate and verify these ideas. Furthermore, the test results were analyzed and discussed. The evaluation method for the strength, the deformation and the skeleton model of between the shear force and the drift angle were proposed.
