Freezing and thawing while causing physical changes in the mechanical properties of concrete，it is bound to change the bond properties between concrete and steel． Center short buried specimens of three concrete strengths C30，C40 and C50 were subjected to the monotonic and cyclic loading tests，the effect of the freeze-thaw damage on concrete and plain bars bond stress-slip curve was studied，and the variation of the peak bond stress，peak slip and residual bond stress under monotonic loading was also analyzed，finally the relationship between the ultimate bond degradation rate and load cycles under cyclic loading was explored．
