EVALUATION OF CALCULATION METHODS OF REINFORCED CONCRETE ELEMENTS SUBJECTED TO BIAXIAL ACTION OF SHEAR FORCES

Abstract

The current design standards for reinforced concrete structures in the Russian Federation do not contain methods for calculating bending elements subjected to biaxial action of shear forces. However, methods for calculating such structures exist and are given in the works of domestic and foreign researchers, as well as in the design standards of past years. This article selects data on the results of 33 tests of beams subjected to action of biaxial shear forces. The results of selected tests were compared with the results of theoretical calculations of the bearing capacity of elements under the biaxial action of shear forces using various analytical methods. A brief overview of existing analytical techniques is provided. A comparison of test results and theoretical calculations is presented in tabular and graphical form. The purpose of the work is to identify existing methods for calculating reinforced concrete bended elements under biaxial action of transverse forces, allowing to obtain load-bearing capacity calculation results that are as close as possible to the test results.
