Q

A fully involved multi-story heavy Timber building is a conflagration breeder for a variety of reasons

A

-Tremendous amount of radiant heat
-numerous large fire Brands carried by tremendous updraft of Fire
-large collapse zones
-lack of sprinklers and most churches and synagogues
-improper fire doors and lack of compartmentation
-sealed up Windows in old mills

22
Q

What has been observed that often remains intact in multi-story heavy Timber buildings after a fire and can potentially be an area Refugee for evacuating firefighters even if the rest of the building collapses

A

Stair shafts

23
Q

In what type of fire would you need a large water supply, numerous heavy-caliber streams, large collapse zone, an extensive brand Patrol downwind, and look to prevent a conflagration

A

Uncontrolled fire in heavy Timber building

24
Q

What is used to attach Timbers to other members and can provide a path for heat to reach the interior of the building

A

Long bolts and nuts

25
Q

Long solid Timbers are hard to obtain so you should be careful for repairs consisting of

A

Spliced Timbers with overlapping joints and metal connectors

26
Q

The only fire protection measure that can reasonably be expected to prevent a disaster and a heavy Timber building

A

Full fire sprinkler protection adequately maintained

27
Q

In newly renovated heavy Timber buildings, particularly in the case of residential units in office spaces in mills, the creation of what is common despite the fact that current building codes do not allow it

A

Creation of ceilings with concealed spaces (enclosures)

28
Q

Most common modern heavy temperature cheese substitute solid Timbers with what

A

Glued laminated Timbers (glulam)

29
Q

What type of construction has been classified as type 4 construction

A

Heavy Timber

30
Q

These buildings were constructed of non-combustible exterior load-bearing walls and wood structural members of specified sizes

A

Heavy Timber Construction

31
Q

Like buildings of ordinary Construction, heavy Timber structures have used

A

Masonry load-bearing walls and wood structural members

32
Q

By definition buildings of heavy Timber construction have what a structural elements

A

Massive Timbers

33
Q

In a heavy Timber structure, the minimum Dimensions required by code for floor beams are

A

6x10 in.

34
Q

Typically incorporates 2x4, 2x6, or 2x8 ft pieces of softwood (pine) laminated (glued) together under pressure and stacked layers with each layer laid perpendicular to the adjacent layers

A

Cross-laminated Timber (CLT)

35
Q

The numbers of layers for CLT can vary from what; usually an odd number for purpose of structural stability

A

3-7

36
Q

These panels can range from 2x10 ft wide and as much as 60ft long

A

CLT panel

37
Q

In 2015, International building code allowed to use of CLT as a component of rated exterior walls, provided the exterior surface of the CLT is covered in what

A

Non-combustible material, gypsum board, or fire retardant treated wood sheathing

38
Q

New category of heavy Timber construction that allows a maximum of 18 stories, provided Mass Timber Wood is covered with gypsum board

A

type 4-A

39
Q

New category of heavy Timber construction that allows a maximum of 12 stories, with limited areas of mass Timber walls and ceilings left exposed

A

type 4-B

40
Q

New category of heavy Timber Construction that allows a maximum of 9 Stories with all of the mass Timber exposed (Timber having been subjected to a 2-hour fire resistance test)

A

type 4-C

41
Q

The traditional form of heavy Timber construction would not be designated as

A

TYPE 4-HT

42
Q

Uses the same concept of manufacturing for typical plywood using thin fiber wood veneers that are placed on top of one another; resins (glue) are applied to the veneer layers and they are passed through both cold and heat presses to create the panel

A

Mass plywood panels (MPP)
(can be as large as 12 ft wide, 48 ft long, and 24 thick)
