Introduction to Steel Design

What are the two broad categories of loads that act on a structure?

• Dead load

• Live load

• Both A and B

• None of the above

What is the primary focus of building codes?

• Structural safety

• Aesthetic design

• Cost efficiency

• Material selection

What is the yield point in structural steel?

• The maximum stress before failure

• The point of permanent strain

• The stress at which unloading occurs

• All of the above

What does the term 'ductile' refer to in steel?

• Ability to withstand high temperatures

• Ability to undergo large deformations before fracturing

• Resistance to corrosion

• None of the above

What is the significance of Young's modulus in structural steel?

• It defines the yield strength

• It measures the stiffness of the material

• It indicates the ductility

• It is irrelevant to structural design

What is the purpose of load and resistance factor design (LRFD)?

• To ensure safety under working loads

• To consider failure conditions

• To apply load factors to service loads

• All of the above

What is the allowable strength design (ASD) approach based on?

• Working load conditions

• Failure conditions

• Material properties

• Cost efficiency

What is a built-up section in structural design?

• A standard rolled shape

• A method to strengthen existing structures

• A type of load

• None of the above

What is the primary requirement of structural design?
