The article gives results of investigations of the stress-strain state of the face layer made of brickwork in the zone of conjugation with overlap at temperature influence. For getting estimated data was used software package ANSYS. There was made a model of brickwork between two reinforced-concrete ceiling panels. Pretest analysis of general stress strain behavior allowed to determine the most dangerous points, where strain changes depending on variable parameters were controlled. After the analysis were got dependence of strain from anchor rigidness and contact area value. Detected relationships could allow select optimal anchor rigidness and value of brickwork cantilever to provide minimal strain in dangerous points. That could rise working life of bricks without any damages.
