description: The purpose of this work is to develop design documentation for a capital construction project and to assess the stress-strain state and reinforcement of load-bearing elements of a monolithic reinforced concrete frame of a high-rise building, determined by various calculation methods, including taking into account the nonlinear properties of the material. The following tasks were formulated and solved to achieve this goal: 1. To study methods for calculating problems in a nonlinear formulation, evaluate the influence of non-linear properties of the material on the stress-strain state of the building frame. 2. To calculate the stress-strain state parameters of the building frame using finite element method in a linear and nonlinear formulation of the problem. 3. To assess the stress-strain state of the building frame for compliance with the conditions of the 1st and 2nd groups of limit states, and select the required reinforcement. 4. To perform a comparative analysis of calculation results using different methods, and evaluate the results obtained. The study consists of assessing the stress-strain state of the building frame, taking into account the physically non-linear properties of the material. Linear and nonlinear calculations were carried out in the LIRA-SAPR software package, the values of internal forces and displacements in the building structures were obtained, and reinforcement was selected. Based on this study, it was concluded that when calculating the building frame, taking into account the physically nonlinear properties of the material in a linear setting, the resulting forces and displacements in the building structures are underestimated, and the required reinforcement area is reduced. With nonlinear calculations, the most accurate results were obtained, reflecting the actual operation of building structures. To achieve the results obtained, the following software packages were used: Autodesk Revit 2022, Autodesk AutoCAD 2021, LIRA-SAPR 2021, SAPFIRE 2021, Twinmotion 2023, SYNCHRO 4D Pro, SmetaWIZARD, Sigma PB, NormCAD, Microsoft Office.
