Ultimate permissible additional hogging of a brick wall during the reconstruction of a historical building

The paper analyzes the possible development of an approach limiting additional deformations of the base of a building during reconstruction. We consider the ultimate permissible value of additional relative hogging in a brickwork wall without reinforcement (f/L)ad,u, which is important for the solution of tasks on the reconstruction of historical buildings. The ultimate values of tensile deformations in a wall can serve as a safety criterion for uneven building settlements. The use of this criterion makes it possible to set more precise values (f/L)ad,u for a brick wall as compared with the values used in Construction Regulations SP 22.13330
