In the article the calculation of the bearing capacity of the inclined cross-sections of the reinforced concrete elements using an external composite reinforcement designing by deformation model DBN V.2.6.-98: 2009 and engineering methodology presented in SNIP 2.03.01-84 are described.
Development and improving for the research methods of reinforced concrete beams are actually one for more researchers. Considering the test of reinforced concrete beams on the shear should be noted that one test is carried out to study the two inclined cross sections of the beam.Usually there destruction of both cross section of the beam appears not simultaneously. We get shear strength only by strength of one inclined cross section. This approach to the researching is economically unreasonable. It is proposed to conduct research inclined cross sections individually.
The priority task for researchers of building structures is developing methods of calculation, which would allow performing constructions calculations with higher accuracy, preserving the reliability of the design. This especially concerns of calculation inclined cross sections of reinforced concrete beams given their sharp, sudden and brittle fracture and difficult stress strain state. Improving methods for calculating will provide the lower expense of materials when designing reinforced concrete structures and allow more efficient using all elements that make the construction.
