Theory of Singly Reinforced Sections

The maximum stress in concrete is approximately reached when the strain value is?

• 0.001

• 0.002

• 0.003

• 0.004

According to IS456:2000, the concrete is assumed to have reached failure when the corresponding strain is?

• 0.0015

• 0.0025

• 0.0035

• 0.0045

The factor of safety of concrete is higher than that of steel because there is a variation in how it is tested (Cube), how it is cast, and how it is manufactured.

• True

• False

In a singly reinforced rectangular beam section, steel reinforcement is provided in:

• Compression Zone

• Tension Zone

• Both Tension and Compression Zone

• Reinforcement not provided

Effective Depth of a Reinforced Concrete Beam section is defined as:

• Distance between extreme compression fibre to extreme tension fibre

• Distance between extreme compression fibre to the neutral axis

• Distance between extreme tension fibre to the neutral axis

• Distance between extreme compression fibre to CG of tension steel reinforcement
