Effect of compressive stresses on strength of inclined sections of out-of-center compressed reinforced concrete elements
Abstract
Currently, designers are faced with the problem of calculating the strength of inclined sections of reinforced concrete columns. The problem is caused by the fact that in SP 63.13330.2018 there are no clear instructions for determining compressive stresses when calculating inclined sections by strength. This circumstance leads to the fact that at high levels of longitudinal compressive forces, the calculation of strength along inclined sections requires in some cases a sufficiently high content of transverse reinforcement, which causes a significant cost overruns of reinforcement and design difficulties. The article describes the main results of the analysis of the research conducted to assess the impact of compressive stresses on the strength of inclined sections of off-center compressed reinforced concrete elements. The issues of calculating the strength of such structures were considered, as well as the methods of domestic and foreign regulatory documents were analyzed. Based on the results of the analysis, the assessment of compliance of the methodology of current regulatory documents with the results of research was performed.
