ranged from 0.10 to 7.50 kN with measured displacements from 0.02 to 0.13 mm. The
differences may also result from the preparation accuracy of models for laboratory
experiments, i.e. during the formation of concrete elements or application of a resin.
Random cracks of relatively small dimensions or other secondary effect and imperfections could appear in solid elements, e.g. during the holes drilling process, could
influence the resultant resistance against the pulling force. Such types of analyzes
and comparative numerical simulations can be helpful for the real assessment of
repairs and reinforcements of three-layer walls in large slab panel buildings in Poland
[20, 21].
It worth to be mentioned that in the simulations performed in ANSYS, the threaded
part of a bonded anchor has been taken into account. It has been done by modification
of standard “frictional” contact type by applying the “virtual thread” conditions. This
software feature is predicted mainly to be used in conventional bolted connections
(e.g. between steel plates) to reduce computational costs. In this paper, it has been
chosen to enhance the accuracy of contact between steel threaded bars with resin
material. This solution is not typical and shall be considered for further detailed
studies.
