0.4%

0.2%

0.1%

Solution:

Indian Standard plain and reinforcedure concrete code of practice is

IS 456 2000

IS 875

IS 1200

IS 10262

Solution:

In RCC structures bars under tension are subjected to

Expansion

Contraction

Both expansion and contraction

None of the above

Solution:

According to IS 456-2000, how is the flexural strength of concrete calculated from its compressive strength?

fcr = 5000√fck

fcr = 0.7√fck

fcr = 0.6√fck

fcr = 0.45 fck Ast

Solution:

Why Beam is called singly reinforced?

Steel is provided in compression zone only

Steel is provided in tension zone only

Anchor bars in compression zone

Both 2 & 3 correct

Solution:

In reinforced concrete, a pedestal is defined as a compression member whose effective length does not exceed its least lateral dimension by more than

12 times

3 times

16 times

8 times

Solution:

An isolated T-beam as shown in the figure is used as a walkway. The beam is simply supported with an effective span of 7.2 m. The effective width of the flange for the given cross-section is:

1200 mm

1020 mm

660 mm

600 mm

Solution:

A rectangular cross-section beam with a span of 8 meters is pre-stressed with a force of 1600 kN. The eccentricity is 50 mm from the neutral axis, and the flexural rigidity is 2.45 × 10¹⁴ N⋅mm². What is the upward deflection (in mm) of the beam?

3.46

2.61

4.62

6.21

Solution:

A pre-tensioned rectangular concrete beam 150 mm wide and 300 mm depth is prestressed with three straight tendons, each having a cross-sectional area of 50mm² to an initial
stress of 1200 Nmm². The tendons are located at 100 mm from the soffit of the beam. If the modular ratio is 6, the loss of prestressing force (in kN) due to the elastic deformation of concrete only is

2.3 KN

4.8 KN

3.4 KN

None
