The anchors comprised post-installed undercut expansion, screw and sleeve expansion types embedded in uncracked concrete. The number and pattern of load cycles followed the ACI recommendations and the ratios of the maximum applied load to the subsequent reduced loads were maintained as recommended by ACI, but the maximum amplitude of each type of load was either 50% or 75% of the relevant static capacity of the anchor. The results of the test show that generally the anchors could sustain the above cyclic load levels without failure, with only one exception, i.e. when subjected to direct shear load equal to 75% of the static shear capacity of the anchor. In the latter case, irrespective of the type of anchor, all the anchors failed within the first 8 load cycles. In each case failure was essentially due to fatigue and this was the only loading case in which full load reversal occurred. In the other cases the anchor residual strength was sometimes higher and sometimes lower than its corresponding static capacity.
