SD500 고강도 철근용 강관 스플라이스 슬리브 철근이음의 구조성능에 관한 실험적 연구

The purpose of this study is to develop the steel pipe splice sleeve system for the high strength reinforcing bar as SD500 and estimate its structural performance. The experimental variables adopted in this study are the development length of rebars, compressive strength of mortar and size of reinforcing bar etc. The results of this study showed that the developed steel pipe splice sleeve for the high strength rebars as SD500 retained the structural performance required in domestic, ACI and AIJ code.
