The long-teim loading tests of reinforced concrete cantilever beams were performed in order to understand and to clarify the mechanism of long-term deflection, especially the increase caused by the slippage of tension steel at the fixed edge on the reinforced concrete member after cracking. In the experiment six pieces of specimens were tested, and the slippage of the steel, crack widths and deflections were examined. Bond analysis equations for members on which different end bending moment acts were also presented. The analysis used the relationships between bond stress and slip proposed in the previous paper. Crack widths and deflections that occured by the slippage of steel were calculated by the bond analysis.
