The previous design of the shear key is designed by considering only the strength of the anchor the body. However, the strength of the anchor portion often be influenced by steel strength of the anchor, as well as the strength of the concrete around the anchor. The purpose of this study was to improve the problem of the existing design methods by considering the performance of the shear key body and the anchor system.
