With regard to the shear design of RCC beams, which of the following statements is/are TRUE?

Your answerSelect all correct options. You can choose more than one.

Excessive shear reinforcement can lead to compression failure in concrete

Beams without shear reinforcement, even if adequately designed for flexure, can have brittle failure

The main (longitudinal) reinforcement plays no role in the shear resistance of beam

As per IS456:2000, the nominal shear stress in the beams of varying depth depends on both the design shear force as well as the design bending moment
