description: This dissertation work presents an approach for processing information obtained in the monitoring process for analyzing the operational loading of a structure in order to restore the stress-strain state (SSS) of a structure, based on known deformations. Reconstruction of SSS is carried out on the basis of the Â«digital twinÂ» of the structure using data on deformations in a real structure. The result of the work is a program executed in three stages. At the first stage, the forces acting on the structure are calculated from the know deformation. The force is calculated by solving the SLAE by the least squares method using a pseudoinverse matrix (Generalized inverse). At the second stage, the SSS of the structure is restored by the know forces. The calculation of SSS is performed by applying known forces to the âdigital twinâ of the structure.At the third and final, the state of a specific structural part is restored from the SSS of the structure. For this, movements and rotations of sufficiently distant structural elements are transferred to a specific structural element. Based on the state of a particular part, it is possible to predict the time of critical deterioration in the state of the structure.
