Design of Steel Structures

1. A 20 mm dia steel bar which is subjected to an axial tension of 2300 kg/cm2 produces a strain of 0.004 cm. If Young's modulus of steel is 2.1 × 106 kg/cm2, the bar is

  1. In the elastic range
  2. In the plastic range
  3. At yield point
  4. None of these

Correct answer: (A)
In the elastic range

2. A beam is defined as a structural member subjected to

  1. Axial loading
  2. Transverse loading
  3. Axial and transverse loading
  4. None of these

Correct answer: (B)
Transverse loading

3. A beam may be designed as a cased beam if

  1. Section is of double open channel form with the webs not less than 40 mm apart
  2. Overall depth and width of the steel section do not exceed 750 and 450 mm respectively
  3. Beam is solidly encased in concrete with 10 mm aggregate having 28 days strength 160 kg/cm2
  4. All the above

Correct answer: (D)
All the above

4. A butt weld is specified by

  1. Effective throat thickness
  2. Plate thickness
  3. Size of weld
  4. Penetration thickness

Correct answer: (A)
Effective throat thickness

5. A circular column section is generally not used in actual practice because

  1. It is uneconomical
  2. It cannot carry the load safely
  3. It is difficult to connect beams to the round sections
  4. All of the above

Correct answer: (C)
It is difficult to connect beams to the round sections

6. A column splice is used to increase

  1. Length of the column
  2. Strength of the column
  3. Cross-sectional area of the column
  4. None of these

Correct answer: (A)
Length of the column

7. A compression member consisting of angle sections may be a

  1. Continuous member
  2. Discontinuous single angle strut
  3. Discontinuous double angle strut
  4. All the above

Correct answer: (D)
All the above

8. A fillet weld may be termed as

  1. Mitre weld
  2. Concave weld
  3. Convex weld
  4. All the above

Correct answer: (D)
All the above

9. A fillet weld whose axis is parallel to the direction of the applied load, is known as

  1. Diagonal filler weld
  2. End fillet weld
  3. Side fillet weld
  4. All the above

Correct answer: (C)
Side fillet weld

10. A major beam in a building structure, is known as

  1. A girder
  2. A floor beam
  3. A main beam
  4. All the above

Correct answer: (D)
All the above
