Design of Reinforcement Concrete Structure

The maximum area of tension reinforcement in beams shall not exceed

• 0.15 %

• 1.5 %

• 4 %

• 1 %

In singly reinforced beams, steel reinforcement is provided in

• Tensile zone

• Compressive zone

• Both tensile and Compressive zones

• Neutral zone

The section in which concrete is not fully stressed to its permissible value when stress in steel reaches its maximum value, is called

• Under-reinforced section

• Over-reinforced section

• Balanced section

• Critical section

The section of the beam having greater width at the top in compression to the width below neutral axis is known as

• Critical section

• T-section

• L-section

• None of these

The effective depth of T-beam is the distance between the

• Center of the flange and top of the tensile reinforcement

• Top of the flange and the center of the tensile reinforcement

• Bottom of the flange and the center of the tensile reinforcement

• Center of the flange and the Bottom of the tensile reinforcement

The diameter of longitudinal bars in a column should not be less than

• 4 mm

• 8 mm

• 12 mm

• 16 mm

The stress strain curve for concrete is considered parabolic by IS code up to a strain of

• 0.0015

• 0.0020

• 0.0030

• 0.0035

According to IS 456, the slenderness ratio for a short column should not exceed

• 12

• 18

• 24

• None of these

Calculate design compressive strength of concrete for M20

• 13.33 N/mm²

• 13.66 N/mm²

• 16.33 N/mm²

• 16.66 N/mm²

State tensile strength of concrete M20 as per IS 456.

• 3.5 N/mm²

• 3.13 N/mm²

• 25000 N/mm²

• 22360 N/mm²
