Annotation: The article presents a comparative analysis of the calculation of compressed-bent pipe-concrete elements by domestic methods of calculation and the European normative document Eurocode 4 «Design of steel-concrete structures». It was considered a multi-storey 16-storey building with a frame frame, dimensions in terms of 3618 m and a height of 64 M. As the supporting elements of the frame were used concrete columns with a diameter of 72014 mm and crossbars I-section 30B1. The calculated combinations of forces in the form of bending moments and longitudinal forces were determined by the results of the calculation of the frame frame model of the building in the program complex LIRA-SAPR 2017. According to the results of static calculation of the frame, the cross-section of the pipe-concrete column (TB) was selected according to the domestic calculation methods and the calculation of the load-bearing capacity of TB by Eurocode 4. In the future, this allowed us to determine the overall difference in approaches and results of the calculation of the bearing capacity of TB by two calculation methods.
Keywords: frame frame, rigid frame Assembly, longitudinal force, bending moment, pipe-concrete element, calculated resistance of concrete in the pipe, reduced flexibility of the element, the coefficient of longitudinal bending, the bearing capacity of concrete compression, the calculated value of the bearing capacity of steel-concrete cross-section bending moment in the plastic stage with full integration.
