The bond relation between steel and surrounding concrete affects cracking behavior in the reinforced concrete structures.
The purpose of the present study is to explore the relation between bond stress and slip under monotonic loading. Test variables are concrete cross section area, steel diameter and concrete compressive strength(f<sub>c</sub>'). According to test results, maximum bond stress is in proportion to f<sub>c</sub>' and the slip where the maximum bond stress occurs increases according to steel diameter and concrete cross section area. The present test results are used for new establiment of bond relation between steel and surrounding concrete. The further researches considering the effect of repeated loading and finite element analysis are necessary to better describe the bona-slip behavior.
