Post-installed anchors are rigorously used in structures such as factory buildings, tunnels, and highway bridges to connect structural and non-structural elements, and are subjected to fatigue loading during service period. The investigation on fatigue behavior of post-installed anchors has been, however, limited up to now. In this paper, the fatigue behavior of post-installed mechanical expansion anchors has been investigated under cyclic tensile loading at dry and wet conditions. The results reveal that residual strength of mechanical anchor was enough comparing to the initial strength under both dry and wet conditions. However, pull-out displacement during fatigue tests under wet condition was larger than that of dry condition.
