높은 마디면적비 철근의 부착강도에 따른 정착설계 연구
Study on the Development Design Criteria of High Relative Rib Area bars
- 발행 : 2006.05.11
초록
Bond between reinforcing bar and the surrounding concrete is made up of three components. There are chemical adesion, friction, and mechanical interaction between the rib of the bar and the surrounding concrete. bond of deformed bars depends primarily on the beraing of rib deformation anainst the surrounding concrete. The final objective of the study is to enhance structural stability, and workability thorough increasing the bond strength between deformed bar and surrounding concrete. The results of this study will be used to shorten bond and development length by
