Staggering of joints in plates or sheathing
Whats a Tail Joist
Flat roof is a simplest roof.
Flat and low slope roofs are used when green roofs are planted is desired so they’re also used for deck space over garages and living areas. What is another name for the small curb that runs around a flat roof so water doesn’t spill off
Parapet
Gable roofs are one of the easiest designs however they are worse for

What are lentils used for
Often called headers are horizontal members used to support loads over a door and window opening they’re usually doubled and sometimes tripled to support heavier loads
Post, beam, plank construction
This type of framing is often used in?
Architectural designs and incorporated into platform framing,

Minimal to no movement
What is a Box Cornice?
F?
CRIPPLES
SOMETIMES CALLED TRIMMERS ARE THE VERTICAL MEMEBR ATTACHED TO STUDS TO SUPPORT LINTELS
A 2x6 wall with fiberglass bat insulation will have studs given an r6 insulation value and
And r9 in cavities between the studs

Wave or cornice
saltbox roof
A?
LINTEL FOR A LOADBEARING WALL
ALSO CALLED A HEADER
A header is above a door or a window and may contained a beam called a
Lintel
D?
UPPER JACK STUD
UPPER JACK STUD ARE CALLED THAT WHEN THEY ARE ABOVE A LINTEL/HEADER
A triangular shaped end of a gable roof is called
Gable
hip or cottage
Platform framing will shrink and settle more than balloon framing by how much
The platform combination of three wall plates and floor joist can cause up to half inch shrinkage per floor level 13 mm
What is a ridge beam
Supports the load of a rafter or floor joist columns that extend to the concrete foundation must support the ridge beam
Which flooring system is used to create a large opening space?
Post, beam, and plank and heavy timber
Which framing system requires components to be designed by registered professional engineer?
Post, beam, and plank construction or if it’s framing’s members are more than 24 in on center
In wood frame buildings what is required when using cement stucco on the exterior finishing
Expansion joints are used at each floor to allow building to move without breaking the stucco
What’s the difference between a crown and a camber
A camber is an intended upward curve built into manufactured beam or girder.
A crown is a lumber defect due to warping
What are two functions of sheathing
Supports finishing, provides lateral support, braces floors, walls or roofs diagonally
What type of framing system usually uses would trusses?
Platform or balloon framing
All frame framing member space greater than 24 in on center must conform to?
Part 4 for the building code structural design which adds significant cost to the project cuz it requires a professional engineer to inspect and sign off the work and design
What style of wall / floor framing is used in the lady smmith vacation cabin
Western platform framing
B?
HEADERS LAYED FLAT BECAUSE NON-LOADING BEARING WALL
G?
LOWER JACK STUD WHEN THEY ARE UNDER A ROUGH SILL
Low-rise buildings are generally three stories or less in height and a regulated by which part of the building code
Part 9
Wood has a r value of about
R1 per inch
Which framing system is the fastest to construct?
Platform framing
Walls that have a sloped top plate are often called
Rake walls as they are normally used under a slope ceiling
Balloon frame construction is also known as Eastern frame construction it is only used in special situation because
It’s very time consuming. And complete balloon framing is rarely used
Balloon framing may be encountered when older buildings are renovated.
What is thermal bridging
An area of significantly lower insulation due to the location of the framing materials
Describe a purlin
Are structural members that run at right angles to the rafters
Shear walls are used to provide
Lateral stability
What is formed when two roofs intersect
Oak Valley is formed when two roof surfaces meet regardless of the slope of the main roof the slope and the valley is less
What is strapping
Is used to prevent the bottom of the joist from twisting so that I can be spaced apart to support ceiling finishes or some types of roofing
What is the difference between post beam and plank construction versus heavy timber construction
Heavy timber construction columns that are 5”
What is a jack stud
Jack studs are studs that are shorter than full studs and they’re referred to as an upper Jack stud when they are above the lintel, and a lower Jack stud when they are under a rough sill of a window opening
Platform and balloon frame construction are very similar and are regulated by part 9 of the building code. Part 9 limits the space in a framing members to maximum of
600 mm 24 in on center
What is a soffit
Is the underside of a building component. The underside of an open stair is also referred to as a stairs soffit.
What is airspace
Air spaces are gaps around the ends of a member of entering a confined area such as a beam pocket. They allow space for air to circulate around the members thus preventing decay
