Originální abstrakt

This work is devoted to investigations on concrete cone failures that are typical for cast-in anchors subjected to tensile loading. Numerical simulations were performed to analyze distribution of the tangential stress, especially in the vicinity of the anchor’s corner where the finite element mesh was refined to obtain accurate results. In accordance with the idea of the maximum tangential stress criterion, the direction where the tangential stress reaches its maximum was investigated. Dependences of this angle on the various depths of the anchor’s embedment were analyzed at selected radial distances from the anchor’s corner, which is a significant stress concentrator in the investigated structure. Obtained results were discussed and several conclusions were stated. Further both numerical and experimental research is planned on this kind of structures.
