Abstract
The shear failure of non-shear-reinforced concrete beams with
normal shear span ratios is observed to be governed in general by
the formation of a critical diagonal crack. Under the hypothesis
that the cracking of concrete introduces potential yield lines
which may be more dangerous than the ones found by the usual
plastic theory, a physical explanation is given for this
phenomenon and a way to estimate the shear capacity of reinforced
concrete beams, based on the theory of plasticity, is described.
The theoretical calculations are shown to be in fairly good
agreement with test results from a large number of experiments
carried out by previous investigators.
