European Conference on Fracture 2024 Investigations on concrete cone failure of a cast-in anchor Lucie Malíková a,b, * , Petr Miarka a,b , Mohammad Sami Al Khazali a,b , Stanislav Seitl a,b a Czech Academy of Sciences, Institute of Physics of Materials, v. v. i., Žižkova 513/22, 616 00 Brno, Czech Republic b Brno University of Technology, Faculty of Civil Engineering, Institute of Structural Mechanics, Veveří 331/95, 602 00 Brno, Czech Republic Abstract 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. © 2025 The Authors. Published by ELSEVIER B.V.

Introduction Anchorage in concrete subjected to tensile loading may fail due to following kinds of failures: pull-out failure, steel failure, side-face blowout, concrete cone failure or splitting of the concrete, see e.g. Eligehausen et al. (2006) or Karmokar et al. (2021). There have been suggested several methodologies, how to assess load-bearing capacity of the anchorage, for instance EN1992-4 (2018), ETAG001 (2010) or fib Bulletin 58 (2011)). Concrete cone failure is one of the most typical modes of failure observed when an anchor is subjected to tensile loading and therefore, it is investigated within this work. This type of failure usually occurs when the tensile capacity of concrete is exceeded, see e.g. Eligehausen et al. (2006), Karmokar et al. (2021) or Nilforoush et al.
