The fatigue effect on the bond behaviour between ultra high modulus (UHM) CFRP plate and steel plate is investigated in this paper. A series of tests on CFRP-steel double strap joints (DSJ) was conducted. Five specimens were tensioned to failure under static loading as control specimens. The other twelve specimens were tested under fatigue loading with load ratios ranging from 0.2 to 0.6 (defined as the ratio of the maximum load in the fatigue test to the average static bond strength of control specimens). After a certain number of fatigue cycles, five specimens failed during fatigue loading and the other seven specimens survived. For specimens failed during fatigue loading, a linear logarithm relationship between the fatigue life and load ratio was achieved. Surviving specimens were later tensioned to failure under static loading. The failure modes and residual strength of surviving specimens were compared with those of control specimens. It was found that the failure modes and residual bond strength of double strap joints were little affected by the fatigue loading.
