Q. Consider the following statements in the light of IS 456 : 2000:

1. There is an upper limit on the nominal shear stress in beams (even with shear reinforcement) due to the possibility of crushing of concrete in diagonal compression.
2. A rectangular concrete slab whose length is equal to its width may not be a two-way slab for certain definable support conditions.

Q. What shall be the maximum area of reinforcement
(i) in compression and (ii) in tension to be provided in an RC beam respectively, as per IS:456?

Q.
A doubly reinforced rectangular concrete beam has a width of 300 mm and an effective depth of 500 mm. The beam is reinforced with 2200 mm

of steel in tension and 628 mm

^{2}

of steel in compression. The effective cover for compressive steel is 50 mm. Assume that both tensioned and compressive steel yield. The grades of concrete and steel used are M-20 and Fe-250 respectively. The stress block parameters (rounded off to first two decimal places) for concrete shall be as per IS : 456-2000.

The depth of neutral axis is

Q. In a singly reinforced concrete beam section, maximum compressive stress in concrete and tensile stress reach their permissible stresses simultaneously. What is such a section called?

Q. A reinforced concrete beam, size 200 mm wide and 300 mm deep overall is simply supported over a span of 3 m. It is subjected to two point loads P of equal magnitudes placed at middle third points. The two loads are gradually increased simultaneously. Beam is reinforced with 2 HYSD bars of 16 mm diameter placed at an effective cover of 40 mm on bottom face and nominal shear reinforcement. The characteristic compressive strength and the bending tensile strength of the concrete are 20.0 N/mm

respectively.

Ignoring the presence of tensioned reinforcement, the value of load P in kN, when the first flexure crack will develop in the beam is
