Question 1

Which system of framing has not been widely used for the last 100 years?&#10;A) post-and-beam framing&#10;B) platform framing&#10;C) timber framing&#10;D) balloon framing

Accepted Answer

Timber framing has not been widely used for the last 100 years.

Question 2

Steel framing has excellent properties for resisting stress from snow, wind, and seismic forces.

Accepted Answer

Steel framing has high strength and stiffness, making it an ideal material for resisting stress from natural forces such as snow, wind, and seismic activity. Therefore, the statement is true.

Question 3

In platform framing, subfloors commonly have a tongue-and-groove pattern in the edge to _____.&#10;A) reduce the need for insulation&#10;B) help minimize floor squeaking&#10;C) allow fewer joists to be used&#10;D) block the entry of mold-laden air into the duct system

Accepted Answer

The tongue-and-groove pattern in subfloors helps to minimize floor squeaking by locking the boards together, creating a more secure and stable base for flooring materials to be installed on top.

Question 4

In residential construction, posts and beams are usually spaced at _____ o.c.&#10;A) 36&#34; (900 mm)&#10;B) 48&#34; (1200 mm)&#10;C) 52&#34; (1300 mm)&#10;D) 60&#34; (1500 mm)

Accepted Answer

In residential construction, posts and beams are usually spaced at 48" (1200 mm) on center. This spacing provides sufficient support for the structure, while also allowing for flexibility in the layout and design of the building.

Question 5

What is an example of a material that can be used during construction to reduce HVAC loads over the life of the structure?&#10;A) slate shingles&#10;B) salvaged framing lumber&#10;C) lumber treated with CCA wood preservative&#10;D) autoclaved aerated concrete (AAC) blocks

Accepted Answer

Autoclaved aerated concrete (AAC) blocks have a high thermal mass, making them an excellent choice for reducing HVAC loads over the life of a structure. They have superior insulation properties and can effectively reduce heating and cooling costs. Additionally, they are fire-resistant, strong, and durable, making them a popular choice for sustainable construction.

Question 6

Masonry units are excellent at resisting forces in tension but very weak at resisting forces from compression.

Accepted Answer

Masonry units are excellent at resisting forces in compression but very weak at resisting forces from tension.

Question 7

AFT systems eliminate nonstructural wood from the building shell and replace it with insulation.

Accepted Answer

AFT systems indeed eliminate nonstructural wood from the building shell and replace it with insulation. This reduces the use of wood and improves the energy efficiency of buildings.

Question 8

A ____ is the connecting of two wythes to form stability within the wall.&#10;A) gambrel&#10;B) bond&#10;C) dormer&#10;D) mansard

Accepted Answer

A bond is the connecting of two wythes (layers of masonry) to form stability within the wall. A gambrel is a two-sided roof with two slopes on each side, a dormer is a structure that projects from a sloping roof, and a mansard is a roof style with two slopes on all four sides.

Question 9

Which statement about modular homes is correct?&#10;A) They are the same as manufactured homes.&#10;B) They are built to meet codes other than the IRC.&#10;C) They are built off site.&#10;D) They are commonly known as mobile homes.

Accepted Answer

Modular homes are built off site in a factory and then transported to the final location where they are assembled on a foundation. Option A is incorrect as manufactured homes are different from modular homes. Option B is also incorrect as modular homes are built to meet the International Residential Code (IRC) or other local codes. Option D is also incorrect as modular homes are not commonly known as mobile homes.

Question 10

Steel framing reduces the risk of thermal bridging through the exterior walls.

Accepted Answer

Steel framing conducts heat, increasing the risk of thermal bridging compared to materials with lower thermal conductivity, such as wood.

Question 11

Insulated concrete forms (ICFs) were originally used for what purpose?&#10;A) providing an energy-efficient wall framing system for an entire structure&#10;B) hearth and chimney construction&#10;C) providing reinforced attic insulation&#10;D) forming foundation walls

Accepted Answer

The answer of Insulated concrete forms (ICFs) were originally used...

Question 15

Which of the following are composed of a continuous core of rigid foam insulation laminated between two layers of structural board with an adhesive to form a single solid pane?&#10;A) structural insulated panels&#10;B) oriented strand boards&#10;C) expanded polystyrene boards&#10;D) steel studs

Accepted Answer

The answer of Which of the following are composed of...
