Abstract

<p> Post-installed anchor is widely spread for the seismic retrofit in existing RC and SRC buildings. Usually, anchor bars are vertically installed in a concrete surface. However, we think that post-installed anchor using diagonal anchor bars improves shear strength. In this research, we confirmed the shear strength of post-installed anchor using diagonal anchor bars through the structural test. In addition, we proposed the evaluation method of shear strength for various failure modes.</p>
