In shear design of an RC beam, other than the allowable shear strength of concrete (τc),
there is also an additional check suggested in IS 456-2000 with respect to the
maximum permissible shear stress (τc max). The check for τc max max is required to
take care of

B. additional shear stress that comes from accidental loading
C. possibility of failure of concrete by diagonal tension
D. possibility of crushing of concrete by diagonal compression
