What is the primary purpose of a composite structure?
A Reduce weight
B Increase strength and stiffness
C Reduce cost
D Improve aesthetics
Composite structures combine steel and concrete to utilize the strengths of both materials. The steel provides tensile strength, while the concrete offers compressive strength, resulting in enhanced load-bearing capacity.
Which of the following is a common type of built-up section in steel structures?
A I-section
B Angle section
C Box section
D Channel section
A box section is a built-up section formed by welding or bolting multiple steel plates together. It is used when standard rolled sections are insufficient for design requirements.
