Question

the horizontal sections of a steel frame are the _________.
a. shell c. suspension
b. i - beams d. rebar
please select the best answer from the choices provided
○ a
○ b
○ c
○ d

Explanation:

To solve this, we analyze each option:

• Option a (shell): Shell structures are curved, not horizontal steel frame sections.
• Option b (I - beams): I - beams are commonly used as horizontal members (beams) in steel frames to support loads horizontally.
• Option c (suspension): Suspension refers to a type of structural system (like suspension bridges), not a horizontal section of a steel frame.
• Option d (rebar): Rebar (reinforcing bar) is used in concrete, not typically as a horizontal section in a steel frame.

So, the correct answer is the one related to horizontal steel frame members, which is I - beams.

Answer:

B. I - beams
