Total questions: 10
Worksheet time: 5mins
What is the main purpose of structural design?
To draw building layouts only
To select suitable materials and determine member sizes for safety
To estimate project cost only
To decorate the structure
Which factor is NOT part of design considerations?
Colour and Decoration
Function and Aesthetic
Safety and Reliability
Economy and Cost-effectiveness
What is a “Code of Practice”?
A manual for site workers
A price list of steel materials
A safety poster for construction sites
A document providing rules and recommendations for design and construction
Which of the following is a major advantage of steel as a construction material?
Heavy and brittle
Easily corrodes without protection
High strength-to-weight ratio
Requires a long construction time
What does the term 'ductile' refer to in steel?
Ability to withstand high temperatures
Resistance to corrosion
The maximum stress before failure
Ability to undergo large deformations before fracturing
What does the Yield Stress (Ys) represent in a stress–strain curve?
The point where stress and strain are proportional
The maximum stress before failure
The total elongation of steel
The stress where plastic deformation begins
What is the significance of Young's modulus in structural steel?
It defines the yield strength
It indicates the ductility
It measures the stiffness of the material
It is irrelevant to structural design
What is the Young’s Modulus (E) of steel approximately equal to?
2,100,000 N/mm²
210 N/mm²
210,000 N/mm²
21,000 N/mm²
Which statement about mild and high strength steel is TRUE?
Both have the same Young’s modulus.
Mild steel has a smaller yield plateau than high strength steel.
High strength steel is weaker than mild steel.
Mild steel is not used in construction.
Which limit state ensures safety against failure or collapse?
Temporary Limit State (TLS)
Aesthetic Limit State (ALS)
Serviceability Limit State (SLS)
Ultimate Limit State (ULS)
