Investigations on concrete cone failure of a cast-in anchor

This paper contains results of a parametrical numerical study performed on an anchor/concrete system. Steel anchors subjected to tensile loading exhibit often so-called concrete cone failure and thus, investigations of this phenomenon are included in this paper. Maximum tangential stress distribution was investigated in the vicinity of a steel anchor embedded in a cylindrical concrete specimen. Finite element analysis enabled to analyze the dependence of both this value and the angle where it occurs on selected parameters, particularly the thickness of the anchor’s basement and the radial distance selected for the investigations. Results and their discussion are presented within this work as a part of an extensive research project on concrete materials and structures.
