• vertical compression

Multiple Choice

Which statement is incorrect? Cavity masonry walls are beneficial because:

• they allow water to drain easily

• their two Wythe's of brick masonry provide added insulation

• they provide a durable façade

• they permit the easy inclusion of insulation

• they are more cost-efficient than solid masonry walls

Multiple Choice

In a CMU loadbearing wall, the weakest component is the:

• mortar

• CMU

• rebar

• concrete fill

Multiple Choice

“Ordinary” construction:

• has walls built upon floors

• allows combustible exterior walls

• is categorized as Type IV according to the IBC

• is very similar to balloon framing

• is also called “mill construction”

Multiple Select

Water permeability of paving can be improved by:

• using permeable pavers

• laying pavers in a herringbone pattern

• spacing conventional paving units and filling in gaps with sand

• All of the answers are correct

Multiple Choice

Which of these is true?

• In hot weather, fresh mortar must not dry out.

• In cold weather, fresh mortar water must not freeze

• In hot weather, masonry may have to be wetted before laying

• All of the answers are correct

Multiple Choice

Trussed joint reinforcement:

• is an effective vertical reinforcement for CMU walls

• is used to reinforce against high loads

• can span across a movement joint

• is laid into the mortar bed

• is used to attach roof trusses to masonry

Multiple Choice

A member on a steel drawing is identified as L5 x 4 x ⅜. This member is:

• a channel

• a wide-flange beam

Multiple Choice

Shear panels or shear walls are sometimes used in steel-framed buildings. Which component of wood light frame construction serves the same function as a shear panel/wall?

• Floor joist

• Exterior wall stud

• Rafter

• Prefabricated roof truss

• Wall sheathing

Multiple Choice

Open-webbed steel joists are usually used in a commercial steel-framed building to support:

Multiple Choice

When insulating light gauge steel walls, care must be taken to:
