A reinforced concrete beam with rectangular cross section (width = 300 mm, effective depth = 580 mm) is made of M30 grade concrete. It has 1% longitudinal tension reinforcement of Fe415 grade steel. The design shear strength for this beam is 0.66 N/mm2. The beam has to resist a factored shear force of 440 kN. The spacing of two-legged, 10 mm diameter vertical stirrups of Fe415 grade steel is _________ mm. (round off to the nearest integer)

In shear design of an $$RC$$ beam, other than the allowable shear strength of concrete $$\left( {{\tau _c}} \right),$$there is also an additional check suggested in $$IS$$ $$456$$-$$2000$$ with respect to the maximum permissible shear stress $$\left( {{\tau _{c\,\,\max }}} \right).$$ The check for $${{\tau _{c\,\,\max }}}$$ is required to take care of
A
additional shear resistance from reinforcing steel
B
additional shear stress that comes from accidental loading
C
possibility of failure of concrete by diagonal tension v
D
possibility of crushing of concrete by diagonal compression

B
Increases parabolically to the neutral axis and then remains constant over the remaining depth.
C
