Annotation
Methods calculation reinforced concrete beams for the bearing capacity inclined sections are given. Considerations were made for calculating the bearing capacity the sections inclined to the longitudinal axis reinforced concrete elements according to the methods the current normative documents, the development international construction magazines, as well as proposals for the calculation by domestic scientists. A comparative analysis the results calculation and experimental data on the bearing capacity sloping to the longitudinal axis has been made, and the corresponding conclusions have been made. And comparison strength characteristics experimental beams from own research.
The result theoretical and experimental research on the basis the calculation of the 162-TDF international European construction journal, calculation model proposed Babich Y.M., Korniychuk O.I. and current normative documents DBN В.2.6-98: 2009 and DSTU B V.2.6-156: 2010 are presented in the article.
Key words
