201 Construction Materials and Methods Flashcard

Front

Which of the following is a common use of metal in construction? Options: Structural framework of commercial buildings, Insulation material in residential homes, Flooring in commercial kitchens, Landscaping features

Back

Structural framework of commercial buildings

Front

Explain why metal is chosen for the structural framework of commercial buildings and as framing members in residential and commercial construction.

Back

Metal provides strength and durability, making it suitable for supporting large structures and withstanding various loads.

Front

Which of the following best describes a wide-flange beam? A steel member with a circular cross section, A steel member with an L-shaped cross section, A steel member used only for decorative purposes.

Back

A structural steel member with parallel flanges joined by a perpendicular web

Front

A steel angle is characterized by which of the following features? L-shaped cross section with equal- or unequal-width legs

Back

L-shaped cross section with equal- or unequal-width legs

Front

Why should penetrations generally be avoided in column support members?

Back

They weaken the member and may cause failure.

Front

Given a scenario where a construction project requires support members to carry both live and dead loads and to meet criteria that wood cannot, what material would be most appropriate to use and why?

Back

Steel, because it can be adapted to meet criteria not possible for wood and is designed to carry live and dead loads.

Front

Which of the following statements best describes the design of steel beams in construction?
Steel beams are designed in a similar fashion to columns and maintain a relative semblance to columns.
Steel beams are always designed differently from columns.
Steel beams are only used for decorative purposes.
Steel beams are never used in modern construction.

Back

Steel beams are designed in a similar fashion to columns and maintain a relative semblance to columns.

Front

How does the thickness (gauge) of steel framing members affect their strength and load capacity?

Back

As the gauge increases, the strength and load capacity increase.

Front

A construction engineer is deciding between two steel framing members for a high-load area. One has a higher gauge than the other. Which member should the engineer choose and why?

Back

The member with the higher gauge, because it can support a greater load.

Front

Which of the following best describes "rebar"?

Back

Steel reinforcing bar with deformations on the surface to allow the bar to interlock with concrete
