Abstract
The results of the study of the damaged condition of the multi-storey building of the service and household unit of the Kursk NPP are presented. The analysis is carried out taking into account the engineering-geological structure of the base and the peculiarities of the construction of the frame. Studied existing damage and deformation of load-bearing and enclosing elements identified their causes, chief among which are nervnoe-tion of sediment foundations, caused by resting one row podkolonnik on the base plate adjacent buildings industrial buildings, as well as the sequence of construction of adjacent buildings. The developed method of strengthening the frame of a multi-storey building, based on the re-support of a number of columns on an additional independent ribbon Foundation, located between the extreme and middle axes, is described. The calculated analysis shows the effectiveness of the proposed reinforcement structure, while additional design solutions are proposed to protect the building from progressive collapse
