This paper describes Asymmetric Friction Connection (AFC) large displacement cyclic sliding tests with two M24 bolts and shims consisting of Grade 80 and Grade 500 Bisalloy steel plates. It was shown that for the low hardness (Grade 80) steel plates that under cyclic testing there was considerable noise, vibration and a temperature increase of up to 30˚C. The compression forces in the bolts decreased by up to 90% and groove depths of up to 2 mm occurred in the shims and up to 6 mm and the sliding plate. The hysteresis loop shape for small cycles up to ±40 mm sliding distance was quite stable and nominal sliding strength divided by the total proof load was 0.64, with minimum and maximum strengths ranging from 0.66 to 1.36 times this. Furthermore, the strength was not constant over the sliding range and degradation occurred after increased cycles of loading, especially cycles to more than 40 mm. For high hardness (Grade 500) shims, the sliding behaviour caused a temperature increase of 16℃, and there was a quiet stable hysteresis loop. The effective coefficient of friction was 0.155 during the initial cycles and the peak coefficient reached 0.18 in the sliding cycles to ±40 mm. The friction coefficient computed as the actual sliding strength divided by the total instantaneous bolt load, was 0.21 to 0.26. Minimum and maximum strength values were 0.92 and 1.15 respectively indicating little variation in strength. After the bolt retightening at the 2nd run, the average effective coefficient of friction was stable with a value of 0.2.
