CMTC 354 TEST 3 EXAM QUESTIONS
AND ANSWERS 100% PASS
Light frame construction - ANS Wood or cold form Steel members comprising the floor wall
and roof systems.
Engineered wood products - ANS Straighter, stronger, lighter, smaller, more flexible
Preservative treated lumber/PTL - ANS All structural supports in contact with ground,
embedded in concrete, exposed to the weather.
Rules for load bearing beams - ANS Code limits amount and place of cuts and boring, and
prohibits cutting, boring, notching engineering material, except where allowed by the
manufacture or unless engineered. No notches allowed in the middle of span L/3. Notches
causes greater weakness than holes.
Ext bearing walls - ANS Holes min 5/8" from edge of stud.
Notches require a nail plate.
Single studs hole max 40% width.
Dbl studs hole max 60% width.
Notch 25% of stud depth.
Exterior wall top plates - ANS Plate must extend beyond 6" notches, minimum 16X1.5"
galvanized plate with at least 8 nails each side.

, Interior non-bearing walls - ANS Notch 40% depth.
Holes 60% width.
5/8" min from edge of stud
Tico nails/hang nails - ANS Better hold, less splitting, easier to drive, won't bend, galvanized.
Fire blocking definition - ANS Limits the spread of flames, smoke, gases in combustible
concealed spaces.
Fire blocking locations - ANS Wall cavities, floor cavities, soffits, stair stringers,
Insulating foam location - ANS Openings, vents, wire holes.
Three materials for fire blocking - ANS 2 X lumber, layers of structural panels, insulation
secured in place.
Studs provide the horizontal fire blocking, except when? - ANS With offset studs, then fire
blocking every 10 feet or less
Why do indoor soffits need fire blocking? - ANS So fire can't spread through vent likes soffits
Where do chases need fire blocking? - ANS At the floor and ceiling Heights
Draft stop - ANS Divide areas into 1000 ft.² or less with 1/2" sheet rock or 3/8" structural
panels on ceiling.
Floor systems include - ANS Support beam/girders, floor joist, floor sheathing, connections
for load path.
