Consider two RCC beams, P and Q each having the section 400 mm x 750 mm (effective depth, d = 750 mm) made with concrete having a Tcmax = 2.1 N/mm2. For the reinforcement provided and the grade of concrete used, it may be assumed that the to = 0.75 N/mm2. The design shear in beam P is 400 kN and in beam Q is 750 kN. Considering the provisions of IS : 456-2000, which of the following statements is true? (a) Shear reinforcement should be designed for 175 kN for beam P and the section for beam Q should be revised. (b) Nominal shear reinforcement is required for beam P and the shear reinforcement should be designing for 120 kN for beam Q.

Question
Consider two RCC beams, P and Q each having
the section 400 mm x 750 mm (effective depth,
d = 750 mm) made with concrete having a Tcmax
= 2.1 N/mm2. For the reinforcement provided and
the grade of concrete used, it may be assumed
%3D
that the t. = 0.75 N/mm2. The design shear in
beam P is 400 kN and in beam Q is 750 kN.
Considering the provisions of IS : 456-2000, which
of the following statements is true?
(a) Shear reinforcement should be designed for
175 kN for beam P and the section for beam
Q should be revised.
(b) Nominal shear reinforcement is required for
beam P and the shear reinforcement should
be designing for 120 kN for beam Q.
