description: Theme of final qualification work: Influence of loss of prestress in construction conditions on the stressed-derformed state (SDS) of monolithic reinforced concrete interior.
Tasks that were solved in the research process:
1. To analyze methods of creating prestressing in monolithic reinforced concrete structures of buildings and structures.
2. To determine the basic methods for calculating prestress losses in prestressed reinforcement as applied to monolithic structures, taking into account the methods of prestressing in building conditions.
3. To assess the effect of these losses on the crack resistance and rigidity of reinforced concrete monolithic overlap structures.
4. To develop recommendations for reducing the loss of prestressing in building structures under construction conditions.
The main types of reinforced concrete structures in which prestressing is created are considered, the analysis of losses, methods of creating prestressing, calculation methods is performed.
A study is made of the effect of prestress losses on the characteristics of the stress-strain state of a monolithic reinforced concrete floor of a multi-storey building.
A model of reinforced concrete flooring of a multi-storey building with the creation of prestressing by tensioning reinforcement on concrete is considered. Work is carried out in construction conditions. The assessment of prestress losses, as well as their influence on the stiffness and crack resistance of floor structures, has been carried out.
Based on the results of the analysis, practical recommendations are given to reduce prestress losses in construction conditions.
Calculations and analysis are made taking into account current norms and rules.
