Application of the Ansys Workbench software package to account for temperature deformations of damaged brick building walls

In the process of monitoring the technical condition of the external brick walls of the five-story building in Perm, made during the cold period of the year, it became necessary to take into account the change in the width of the opening of existing cracks due to air temperature fluctuations [1,2]. The main cause of the existing wall damage is the uneven deformation of the base in the first years of operation due to the insufficient bearing capacity of the soil [3]. During the observations of the building, the width of the opening of existing cracks in the outer walls changed both in the larger and smaller directions. At the same time, the appearance of new cracks was not fixed, which cast doubt on the version of the negative effect of geological processes at the base of the foundations. To confirm the hypothesis of temperature deformations of walls, an accurate quantitative assessment of changes in the width of crack opening was required by computer simulation of the stressed state of walls due to air temperature fluctuations with subsequent comparison of results with monitoring data. In the software complex Ansys Workbench, the walls of the building are calculated for the temperature effects. Calculations confirmed that from the temperature drop in the brickwork of the walls of the surveyed building there are tensile stresses, the concentration of which coincides in localization with the actual trajectories of cracks. The calculated values of crack opening, obtained as a result of computer simulation, are very close to the actual values measured during monitoring.
