1. Which load combination is used for strength design according to
typical structural design standards?
A. 1.0D + 1.0L
B. 0.9D + 1.6L
C. 1.2D + 1.6L
D. 1.4D
Answer: C
This is a common LRFD strength load combination for dead and live
loads.
2. In reinforced concrete design, the purpose of stirrups is primarily
to resist:
A. Flexure
B. Torsion only
C. Shear
D. Axial load
Answer: C
Stirrups are provided mainly to resist shear and control diagonal
cracking.
, 3. The modulus of elasticity of structural steel is approximately:
A. 20 GPa
B. 70 GPa
C. 200 GPa
D. 400 GPa
Answer: C
Structural steel has an elastic modulus of about 200 GPa (29,000 ksi).
4. For a simply supported beam with a uniformly distributed load,
the maximum bending moment occurs at:
A. One-quarter span
B. Midspan
C. One-third span
D. At the supports
Answer: B
For uniform loading, the maximum bending moment occurs at midspan.
5. Which soil parameter is most critical for estimating settlement of
shallow foundations?
A. Angle of internal friction
B. Cohesion
C. Modulus of elasticity
D. Unit weight
Answer: C
Settlement calculations depend heavily on soil stiffness (modulus of
elasticity).
, 6. In steel design, buckling of columns is primarily influenced by:
A. Yield strength
B. Length and end conditions
C. Cross-sectional area only
D. Applied moment
Answer: B
Column buckling capacity depends on effective length and boundary
conditions.
7. Which type of load is considered a transient load?
A. Dead load
B. Live load
C. Self-weight of structure
D. Soil pressure
Answer: B
Live loads vary with use and occupancy and are considered transient.
8. The neutral axis of a reinforced concrete beam under positive
bending lies:
A. At mid-depth
B. Above the compression face
C. Within the compression zone
D. At the level of tensile steel
Answer: C
The neutral axis lies within the compression zone of concrete.
, 9. Which structural system primarily resists lateral loads in a braced
frame?
A. Beams
B. Columns
C. Diagonal braces
D. Slabs
Answer: C
Diagonal bracing provides lateral resistance in braced frames.
10. The effective length factor (K) for a column pinned at both
ends is approximately:
A. 0.5
B. 0.7
C. 1.0
D. 2.0
Answer: C
Pinned-pinned columns typically have K ≈ 1.0.
11. Which material property governs serviceability deflection in
beams?
A. Yield strength
B. Ultimate strength
C. Modulus of elasticity
D. Density
Answer: C
Deflection is controlled by stiffness, which depends on modulus of
elasticity.
