Characteristics of bond between steel and concrete was discussed in this paper. The main purpose of this study is to establish the way how to derive the bond stress distribution along the reinforcing steel embedded in concrete under a arbitrary condition. The analytical methods developed here are based on the relationships between bond stress (τ) and the relative movement of steel to surrounding concrete (s), which were obtained empirically. Two test methods was adopted independently to obtain the τ-s relationship. The developed theory was applied to the case of embedded rod test specimens where a reinforcing bar was em bedded in a sufficiently long and big concrete prism and the load was introduced by pulling the both ends of the bar. The test results of embedded rod tests and the analytical solution applied to them were compared and it was shown that the developed theory was quite reasonable in the case where deformed bars were used and gave us a tool to appreciate the problems of bond.
