description: The given work is devoted to the modeling of structures made of prestressed concrete and the
analysis of their stress-strain state in the SOFiSTiK software package. The research set the following
goals:
1. The study, synthesis and analysis of existing tools and methods for calculating prestressed
structures.
2. Study and evaluation of post-tension modeling techniques using SOFISTIK interfaces.
3. The study and evaluation of pre-stress modeling techniques using the CADINP software
environment.
4. Justification of the applicability of the calculation results in the SOFISTIK software package.
5. Analysis of the phenomenon of genetic nonlinearity in the process of creating prestress.
6. Development and analysis of design models for the coating of an industrial building using
conventional and prestressed concrete.
7. Assessment of the feasibility and appropriateness of using the SOFiSTiK software package
and the CADINP programming language for the structural analysis of buildings and
structures made of prestressed reinforced concrete.
The work describes the methodology for modeling structures of prestressed concrete in the
SOFiSTiK software package. Verification calculation was made, confirming the correctness of
considering effect of prestressing, calculation of the first and second stress losses. To analyze the
phenomenon of genetic nonlinearity, a solution to the Perelmuter-Slivker calculation task is obtained,
which correlates with the correct results. In order to test the methodology, a model of ceiling of an
industrial building was created and calculated. In conclusion, the key advantages of the methodology in
comparison with the classical methods of modeling prestressing are noted.
