What two thing effect fuel load?
Occupancy and Use
Two methods of heat transfer:
Radiation and convection
_____ usually involves the transfer of heat through movement of hot smoke and fire gases.
Convection
_____ is the transfer of heat energy through space by electromagnetic waves.
Thermal radiation
A chemical process of oxidation that occurs at a rate fast enough to produce heat and usually light in the form of a glow or flame.
Combustion.
_____ construction is classified by the presence of Noncombustible structural components that have fire resistive rating within a specified range.
Type I
_____ construction allows a wider range of materials that Type I.
Type II
_____ construction has been commonly referred to as “ordinary construction”. Exterior walls of masonry.
Type III
_____ construction is commonly known as heavy-timber or “mill” construction.
Type IV
_____ construction is primarily used for aesthetic. Structural components are allowed to be of combustible construction.
Type V
The maximum amount of heat that can be released if all fuel is consumed.
Fire Load
Total amount of thermal energy that could be generated by the combustion reaction if a fuel were completely burned:
Heat of Combustion
The force of _____ is the most common load imposed on a structure via the weight of the structures components, contents, and any occupancy activity.
Gravity
Load perpendicular to the cross section of the structural member.
Eccentric
Load applied off-center from the cross section of the structural component and at an angle to or in the same plane as the cross section.
Torsional
Load applied to the center of the cross section of a member and perpendicular to that cross section.
Axial
_____ load is fixed in location and quantifiable.
Dead load
_____ load is not fixe or permanent.
Live load
_____ loads are steady or applied gradually.
Static loads
_____ loads involve motion and are capable of delivering energy greatly in excess of the weight of the object involved.
Dynamic Loads
_____ are structural members designed to support an axial load.
Columns
____ is a curved structural member with primarily compressive interior stresses.
Arch
_____ are framed structural units made up of a group of triangles in one plane.
Trusses
_____ framing uses a series of vertical elements to support horizontal elements that carry transverse loads.
Post and Beam Construction
A _____ structural system is characterized by columns and beams reinforced to transmit the bending stress through joints.
Rigid Frame
_____ consist primarily of an enclosing, waterproof surface.
Surface Systems
_____ are similar to fabric tents, but differ in that they are intended to he permanent structures.
Membrane Structures
Stairs that are NOT part of the means of egress are referred to as _____.
Convenience Stairs
_____ elevators carry people.
Passenger
_____ elevators carry resources that may be bulky or heavy.
Freight
_____ elevators are passenger elevators designed to also carry freight.
Service
_____ elevators operate via fluid forced, under pressure, into a cylinder containing a piston or ram.
Hydraulic
_____ elevators use a hoisting cable and drum.
Electric
_____ elevators use a hoisting cable wound on a drum located in a motor room.
Drum
_____ elevators are the most common type of elevator in buildings over six stories. They use counter weights.
Traction
_____ elevators feature controls that may be remote from the elevator system.
Machine Room-Less
_____ are small freight elevators that move along a hoistway and transport items of small weight and size between floors.
Dumbwaiters
_____ are used for express elevators that serve the upper elevator zones in tall buildings.
Blind Hoistways
Fully enclosed escape stairway that exits directly onto a public way.
Smoke tower
_____ expand upon exposure to heat and create a thick, puffy coating that insulates the wood surface form heat and excludes oxygen form the wood.
Intumescent paint
_____ coatings form a thick, noncombustible coating over the surface of the wood.
Mastic coatings
_____ procedures include standardized methodologies that are intended to control as many variables as possible and yield meaningful results.
Criterion-referenced testing
A series of barriers designed to keep flames, smoke, and heat from spreading between spaces.
Compartmentation
_____ are self-supporting with respect to vertical loads.
Freestanding walls
_____ are interior walls that do not qualify as fire walls but are used to subdivide a floor or area of a building.
Fire Partitions
_____ is a style of wall that is designed to separate the interior environment from the exterior. These are nonload-bearing.
Curtain Wall
_____ are the most common means for protecting openings through fire rated walls.
Fire Doors
Class __ Fire Door: Openings in fire walls.
A
Class __ Fire Door: Openings in vertical shafts and openings in 2-hour rated partitions.
B
Class__ Fire Door: Openings between rooms and corridors having a fire resistance of 1 hour or less.
C
Class __ Fire Door: Openings in exterior walls subject to severe fire exposure from the outside of a building.
D
Class __ Fire Door: Openings in exterior walls subject to moderate or light exposure from the outside.
E
_____ fire doors commonly protect stairwell enclosures and corridors.
Swinging fire doors
_____ are driven into the ground and support a load by transferring the load either through friction with the surrounding soil, or trough contact with rock or other stable soil.
Piles
_____ and _____ secured with mortar are the materials most commonly used for foundational walls.
Concrete and masonry
