description: The subject of the graduate qualification work is Â«Assessment of stress-strain state of bendable reinforced-concrete elements of a high-rise building using diagram methodsÂ».
This paper provides a comparative analysis of the results of calculations of reinforced concrete bending elements of concrete of Ð30 and Ð70 strength classes with different methods of taking into account physical nonlinearity of material deformation and development of recommendations for design calculations using concrete and reinforcement deformation diagrams.
Objectives of the study:
1. Analysis of engineering and diagram methods of calculation of reinforced concrete structures on the basis of normative and literary sources;
2. Performance of comparative calculations of reinforced concrete beams made of concrete of classes Ð30 and Ð70 according to SP 63.13330-2018;
3. Performance of comparative calculations of reinforced concrete beams made of concrete of Ð30 and Ð70 classes taking into account physical nonlinearity of deformation;
4. Comparative analysis of calculation results, evaluation of efficiency of considered calculation methods, development of recommendations for their application.
In this work, calculations of reinforced concrete beams made of concrete of Ð30 and Ð70 classes were carried out according to the method with different versions of accounting for physical nonlinearity of concrete and reinforcement deformation. Comparative analysis of calculations on limit states was carried out, reinforcement was selected.
On the basis of comparative analysis of various methods, the method using deformation diagrams was considered to be the most effective. Recommendations are given for using this method in real design.
