![The width and effective depth of a reinforced
concrete beam is 250 mm and 440 mm
respectively. The beam is provided with 4 number
of 20 mm bars in the tension zone. The beam is
subjected to a shear force of 150 kN (Factored).
Check the requirement of shear reinforcement and
provide if required. Grade of concrete is M 20 and
that of steel is Fe 415. The shear strength of
concrete for different percentage of tensile steel
are as below. 8mm diameter vertical stirrups are
available.
