CHAPTER 4 - BUILDING CONSTRUCTION Flashcards
I wouldn’t structural panel formed by gluing and compressing wood strands together under pressure. This material has replace plywood and planking and the majority of construction applications.
Oriented strand board
Wood with high moisture content.
Greenwood
Bricks, blocks, stones, and unreinforced and reinforced concrete products.
Masonry
Walls with a surface layer of attractive material laid over a base of common material.
Veneer walls
Expansion of excess moisture with and masonry materials due to exposure to this sheet of a fire, resulting in Temple forces within the material, and causing it to break apart.
Spalling
Structural support made from a long steel bar that is bent at a 90° angle with flat or angular pieces welded to the top and bottom.
Lightweight steel truss
A non-loadbearing wall, often of glass and steel, fixed to the outside of the building and serving especially as cladding.
Curtainwall
Short for reinforcing the bar. Steel bars placed in concrete forms for the cement is poured. adds considerable strength.
Rebar
Type of building construction that uses renewable, environmentally friendly or recycled materials. Also known as natural or green construction.
Hybrid construction
Steel structural members that are covered with either spray on fireproofing or fully encased in underwriters limited tested in improved system
Protected steel
Rating assigned to a material or assembly after standardized testing by an independent testing organization. Identifies the amount of time and material or assembly will resist a typical fire, as measured on a standard time temp curve.
Fire resistance rating
Solid materials, such as wood blocks, used to prevent or limit the vertical and horizontal spread of fire and the products of combustion in the hollow walls or floors, above false ceilings, in penetrations for plumbing or electrical installations, in penetrations of a fire rated assembly, or cockloft and crawlspaces
Fire stop
Walls of the building by design carry at least some part of the structural load of the building in the direction of the ground base.
Loadbearing wall
And upright post in the framework of a wall for supporting sheets of laugh and plaster, wallboard, or similar material.
Stud
Walls, usually interior, that support only its own weight.
Non-loadbearing wall
Interior nonload bearing wall that separates the space into rooms.
Partition wall
Fire rated wall with a specific degree of fire resistance, built of fire resistant materials and usually extending from the foundation up to and through the roof of a building, that is designed to limit the spread of the fire with in the structure or between adjacent structures.
Fire wall
A loadbearing wall shared by two adjacent structures
Party wall
Portion of the exterior walls of the building that extends above the roof. A low wall at the edge of the roof.
Parapet
The horizontal line at the junction of the top edges of two sloping roof surface
Ridge
The edge of a pitched roof that overhangs an outside wall.
Eave
Inclined beam that supports A roof, runs parallel to the slope of the roof, and to which the roof decking is attached
Rafter
Metal or wooden plates used to connect and strengthen the joints of two or more separate components into a load bearing unit
Gusset plates
Horizontal structure remember I used to support a ceiling or floor. Drywall materials are nailed or screwed to the ceiling. And the subfloor is nailed or screwed to the floor
Joists
Structural supports constructed of 2 x 3” or 2 x 4” members that are connected by gusset plates
Light weight wood truss
A trust constructed with the top and bottom chords parallel. These dresses are used as floor joists in multi story buildings and as ceiling joists and buildings with flat roofs.
Parallel cord truss
Horizontal member between trusses that support the roof
Purlin
Concealed space between the top floor and the roof of the structure
Cock loft
Weight of the structure, structural members, building components, and any other features permanently attached to the building that are constant and immobile
Dead load
A second roof constructed over an existing roof
Rain roof
Items within a building that are movable but are not included as a permanent part of the structure; merchandise, stock, furnishings, occupants, firefighters, watering used for fire suppression are examples of this. Force placed upon a structure by the addition of people, objects, or whether
Live load
Continuous an unobstructed way of exit travel from any point in a building or structure to a public way, consisting of three separate and distinct parts: exit access, exit, and exit discharge.
Means of egress
Masonry is the most common building material in North America. True or false?
False – wood is most common
The effect of heat on the metal will depend on the type of metal and if it is exposed or covered. True or false?
True
Wrought iron is the primary material used in the construction of large modern buildings. True or false?
False – steel is the primary material
Manufactured structures are required to conform to model building codes. True or false?
False – manufactured homes are not required to conform to the model building codes
Wall rated assemblies may be continuous from one floor to the bottom of the next floor. True or false?
True
There is always an external sign, like a soft roof, before roof collapse. True or false?
False – OSB and plywood sheathing could fail without warning
Roof penetrations and openings can allow firefighters to gain access to attics. True or false?
True
When off, solar panels retain no electricity. True or false?
False – even if power is off they retain/produce power
Rain roofs may hide heating, ventilation, and air-conditioning units that contribute to collapse potential. True or false?
True.
Roof mounted equipment is never hidden from plain sight. True or false?
False – they may be under rain roofs
Smoke proof stair enclosures are required in all buildings. True or false?
False – they are only required in certain circumstances
Fire doors must pass a test by a third-party testing agency. True or false?
True
