methodology.

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.
