In a reinforced concrete beam, what should the spacing of vertical stirrups be in terms of effective depth, to ensure adequate shear reinforcement as per IS 456:2000?
1
It should not exceed 0.75 times the effective depth (d) of the beam.
2
It should not exceed twice the effective depth (d) of the beam.
3
It should not exceed the effective depth (d) of the beam.
4
It should not exceed 1.5 times the effective depth (d) of the beam.
