Civil Engineering GATE 2023 Set-2 Questions with Answer

Ques 27 Structural Analysis

When a simply-supported elastic beam of span L and flexural rigidity El (E is the modulus of elasticity and l is the moment of inertia of the section) is loaded with a uniformly distributed load w per unit length, the deflection at the mid-span is
Δ_0 = (5/384)(wL^4)/(EI)
. If the load on one half of the span is now removed, the mid-span deflection

A

reduces to Δ_0/2

B

reduces to a value less than Δ_0/2

C

reduces to a value greater than Δ_0/2

D

remains unchanged at Δ_0



Ques 28 Structural Analysis

Muller-Breslau principle is used in analysis of structures for

A

drawing an influence line diagram for any force response in the structure

B

writing the virtual work expression to get the equilibrium equation

C

superposing the load effects to get the total force response in the structure

D

relating the deflection between two points in a member with the curvature diagram in-between



Ques 29 Structural Analysis

In the frame shown in the figure (not to scale), all four members (AB, BC, CD, and AD) have the same length and same constant flexural rigidity. All the joints A, B, C, and D are rigid joints. The midpoints of AB, BC, CD, and AD, are denoted by E, F, G, and H, respectively. The frame is in unstable equilibrium under the shown forces of magnitude P acting at E and G. Which of the following statements is/are TRUE?

A

Shear forces at H and F are zero

B

Horizontal displacements at H and F are zero

C

Vertical displacements at H and F are zero

D

Slopes at E, F, G, and H are zero



Ques 30 Structural Engineering

M20 concrete as per IS 456: 2000 refers to concrete with a design mix having

A

an average cube strength of 20 MPa

B

an average cylinder strength of 20 MPa

C

a 5-percentile cube strength of 20 MPa

D

a 5-percentile cylinder strength of 20 MPa



Ques 31 Structural Engineering

With regard to the shear design of RCC beams, which of the following statements is/are TRUE?

A

Excessive shear reinforcement can lead to compression failure in concrete

B

Beams without shear reinforcement, even if adequately designed for flexure, can have brittle failure

C

The main (longitudinal) reinforcement plays no role in the shear resistance of beam

D

As per IS456:2000, the nominal shear stress in the beams of varying depth depends on both the design shear force as well as the design bending moment



Ques 32 Surveying

The magnetic bearing of the sun for a location at noon is 183°30′. If the sun is exactly on the geographic meridian at noon, the magnetic declination of the location is

A

3°30′W

B

3°30′E

C

93°30′W

D

93°30′E



Ques 33 Surveying

If the size of the ground area is 6 km × 3 km and the corresponding photo size in the aerial photograph is 30 cm × 15 cm, then the scale of the photograph is 1: (in integer).


20000 is the correct answer.

B

(braking distance required to come to stop) - (distance travelled during the perception-reaction time)

C

(braking distance required to come to stop)

D

(distance travelled during the perception-reaction time)



Ques 35 Transportation Engineering
