Abstract
Coefficients for rectangular stress diagram used in various regulations and methods are analyzed. These coef-ficients are compared with experimental data presented by other authors. It was revealed that theoretical and experi-mental values of some coefficients for rectangular stress diagram when concrete classes are high are less than pos-sible minimum values obtained using triangular stress dia-gram. The limit compression zone depth value according to STR 2.05.05:2005 and according to hypothesis of plane sections was analyzed as well. It was determined that the depth of these diagrams differs quite substantially.
