ABSTRACT
In accordance with the requirements of domestic standards, when reconstructing historical buildings or adapting cultural heritage objects with load-bearing walls made of brickwork for modern use, it is necessary to limit the amount of additional deformation of the ground base of the building. For St. Petersburg, this issue is particularly important due to the complex engineering and geological conditions. The values of the maximum deformation of the base are set by the norms depending on the category of the technical condition of the brick building, without reference to any of its structural features. The article analyzes the methodological advantages and disadvantages of this approach. For stone buildings-monuments, it is recommended to introduce an additional criterion for ensuring mechanical safety – the maximum additional width of the crack opening. Based on this criterion, for each monument by reverse calculation, it is possible to clarify the eigenvalues of the maximum additional deformations of the base and assess the need to strengthen the stone structures from the calculated sediments. An example of such a calculation is given for the object of cultural heritage “Barracks of the Pavlovsky Regiment” in St. Petersburg.
