Abstract

The paper studies the load-bearing capacity and stability of reinforced concrete composite frame without collar beams during linear and physically nonlinear operation of its materials under static loading.
Purpose: The strength analysis of a reinforced concrete frame without collar beams using the coefficient of structural strength in the linear calculation and use factor by bearing capacity determined by the limit surface of elements, as well as linear and physically nonlinear stability based on the limit repulsion of the system.
Methodology: The computational substantiation of the bearing capacity and stability of the reinforced concrete frame at different stages of materials performance, is carried out in the Ing+2021 MicroFe program with the proposed finite element spatial model.
Research findings: The structural strength and bearing capacity are calculated for reinforced concrete composite frame without collar beams during linear and physically nonlinear operation of its materials under static loading.
