Outline of Final Research Achievements

Post-installed anchor is widely-spread for the seismic retrofit in existing reinforced concrete buildings. Usually, anchor bars are vertically installed in a concrete surface. However, when shear resistance is expected in post-installed anchors, installing the anchor bars diagonally changes the resistance mechanism such that the anchor bar is subject to forces along the axial direction, which is predicted to produce great resistance. In this research, first, we confirmed the shear strength of diagonal post-installed anchors under the complex stresses. Next, we confirmed the mechanical behavior of reinforced concrete columns with extended wing wall strengthened by diagonal post-installed anchor subjected to seismic action. From the structural tests, it was shown that the column which used diagonal post-installed anchors clearly improves ultimate shear strength. Moreover, I showed that proposed evaluation method of the ultimate strength the test result well.
