Shear strength of reinforced concrete beams
Although the topic of shear strength in reinforced concrete beams has
been treated for a long time by several research bodies, the calculation
models available to practicing engineers do not allow to calculate
precisely the shear strength of a given beam.
The research performed by the Structural Concrete Laboratory have shown that the uncertainties in the shear strength are related to the distribution of the shear on the depth of the section, the ability of the tension and compression chords to carry a part of the shear force and the effect of a simultaneous contribution of a transverse bending. These effects are currently being investigated experimentally and analytically.
