Why you might get asked this:
Tests fundamental structural/geotechnical knowledge critical for ensuring designs are safe and reliable in civil engineering.
How to answer:
Define FoS as the ratio of ultimate strength/load to actual working stress/load and explain its importance for accounting for uncertainties.
Example answer:
The Factor of Safety (FoS) is the ratio of a structure or material's ultimate capacity to the actual load or stress it will experience in service. It's important because it accounts for uncertainties in material properties, applied loads, analysis methods, and construction variations, ensuring a margin of safety against failure in civil engineering structures.
27. What is prestressed concrete?
Why you might get asked this:
Evaluates your knowledge of advanced concrete technologies used for specific applications in civil engineering.
How to answer:
Explain it's concrete where internal compressive stresses are introduced intentionally using tendons to counteract tensile stresses from external loads.
Example answer:
Prestressed concrete is concrete where high-strength steel tendons are tensioned, either before (pre-tensioning) or after (post-tensioning) the concrete sets. This pre-applied compression counteracts the tensile stresses that would normally develop under service loads, allowing for longer spans and more efficient use of material in civil engineering structures like bridges or beams.
28. Explain development length.
Why you might get asked this:
Tests understanding of reinforced concrete design principles related to transferring stress from rebar to concrete.
How to answer:
Define it as the minimum length rebar must extend into concrete to anchor properly and develop its full tensile strength via bond stress.
Example answer:
Development length is the minimum required embedment length of reinforcing steel in concrete to ensure that the bar can develop its full yield strength through bond stress without slipping. It's crucial in reinforced concrete design to properly transfer forces from the concrete to the rebar and prevent structural failure at connections or splices in civil engineering elements.
29. What is the difference between GPS and Total Station in surveying?
Why you might get asked this:
Assesses knowledge of common surveying equipment used in civil engineering for site layout and mapping.
How to answer:
Explain GPS uses satellites for global positioning, while Total Station uses optical/electronic methods for precise local angle and distance measurements.
Example answer:
GPS (Global Positioning System) uses satellite signals to determine a point's position on Earth, suitable for large-area mapping and control points. A Total Station is a terrestrial surveying instrument that measures angles and distances from a known point to targets, providing high precision for detailed site layout, topographic surveys, and construction staking in civil engineering projects.
30. Common foundation types for residential buildings?
Why you might get asked this:
Tests basic knowledge of common structural elements used in residential civil engineering construction.
How to answer:
List and briefly describe common shallow foundation types like strip footings, pad footings, and raft/mat foundations.
Example answer:
Common residential foundation types are typically shallow foundations. These include strip footings (continuous support under load-bearing walls), pad footings (isolated supports under columns), and raft or mat foundations (a large slab covering the entire building area, used for weak soils or heavy loads). Selection depends on soil conditions and building loads in civil engineering practice.
