Abstract: In the modern civil engineering field the anchorages play a very important role. In fact, the standardization of industrial process, like precasting industry, puts in evidence the need to develop modular elements. For the connections of these elements can be used: anchoring industrial systems (chemical anchors, undercut anchors, ecc.), cast-in-place anchors (designed before the casting of concrete). These anchors are often short cast-inplace anchors. They are used for fixing anchored panels, for fixing other elements to structure (publicity panels for example), or for fixing operating machine to ground.
The anchors are subjected to cyclic loads. In particular, in the case of blocking operating machine, problematic of fatigue is present and can be predominant.
In this paper the fatigue behaviour of three types of short cast-in-place anchors is described. For this research have been used: anchor bolt, ribbed and rod bar. The experimental results permit to describe the evolution of some variables like displacement, stiffness, dissipated energy during the fatigue life.
The correlation between the load-displacement curve during the static pull-out test and the cyclic behaviour of anchor is also discussed.
