Civil Engineering MCQs
Civil Engineering MCQs cover structural analysis, concrete technology, geotechnical, transportation, fluid mechanics, materials, and surveying, helping PPSC, FPSC, NTS candidates and graduates strengthen theory, apply concepts, and excel in engineering exams, interviews, and professional assessments.
Q: Prestressed concrete is used to
A) Increase height
B) Reduce cost
C) Introduce tension to resist loads
D) Improve aesthetics
✅ Correct Answer: C
Explanation: Prestressing induces internal stresses to counter external loads, enhancing load capacity.
Q: A cantilever beam is supported at
A) Free ends
B) Centre only
C) Both ends
D) One end
✅ Correct Answer: D
Explanation: Cantilevers are fixed at one end and free at the other to resist bending.
Q: The density of steel used in RCC design is taken as
A) 8050 kg/m³
B) 7850 kg/m³
C) 7500 kg/m³
D) 8200 kg/m³
✅ Correct Answer: B
Explanation: Standard density of steel is 7850 kg/m³ for structural calculations.
Q: Boussinesq’s theory is used in soil mechanics to determine
A) Vertical stress distribution
B) Shear strength
C) Compaction
D) Settlement
✅ Correct Answer: A
Explanation: It predicts how vertical stress is distributed in soil due to surface loads.
Q: A well point system is commonly used for
A) Excavation
B) Pile driving
C) Cleaning
D) Dewatering
✅ Correct Answer: D
Explanation: Well point systems lower the groundwater table for dry excavation work.
