Chapter 14: Building Construction

Question 1

5 Types of building Construction

Answer 1

I : Fire Resistive Consrtuction
II : Non/Limited Combustible
III : Ordinary Construction
IV : Heavy Timber 
V ; Wood Framed Construction

Question 2

I : Fire Resistive Consrtuction

Answer 2

Made with non combustible material or with fire-restive ratings that all material s to with stand the effects of fire and prevent spread from floor to floor

think pound maker

Question 3

II : Non/Limited Combustible

Answer 3

similar to type I but to materials used have lower ratings.

think training school

Question 4

III : Ordinary Construction

Answer 4

outside materials have non or limited combustible materials but the interior structural members are partial or completely made of wood

think strip malls….

Question 5

IV : Heavy Timber

Answer 5

exterior walls made of non combustible materials and interior components made of large dimensional lumber with no concealed spaces
columns >8” thick
Girders >6” thick

think board walk building

Question 6

V ; Wood Framed Construction

Answer 6

building almost completely made of small dimensional wood wood products

almost all single family homes

Question 7

Balloon Frame:

Answer 7

Unobstructed channels run between the studs from the seller to the attic, and between the joists from wall to wall

Question 8

Platform Frame

Answer 8

This has built-in fire stops between each floor; there are no continuous vertical spaces

Question 9

5 factors that affect woods ignition

Answer 9

• Density
• Size and Form
• Moisture content
• Rate of Preheating
• Ignition Source

Question 10

types of Engineered wood…

Answer 10

Plywood, Splice Timbers, Glue Lam Beams, Planks< Chipboard, OSB, Particleboard, MDF,

Question 11

8 types of LOADS

Answer 11

Fuel Load:amount of potential fuel
Structural Load: Forces that work against structures ability to stand
Dead Load: Building and all attached fixtures
Live Load: Weight of content, occupants, snow/Rain
Impact Load: short 1 time bursts of pressures
Static Load: Gradual or constant pressures over time
Repeated Load: intermittent pressures applied over time

Internal Forces:

Question 12

Internal Forces

Answer 12

Compression, Tensile, Shear, Concentrated, Axial, Torsional, Suspended Loads

Question 13

Truss Hazards

Answer 13

the strength of connection: when one fails they all fail

Question 14

Load bearing & non load bearing walls

Answer 14

Load bearing walls: support the weight of building laterally along their length in addition to their own weight.

Non Load Bearing Walls: Walls support only their own weight

Question 15

6 types of walls

Answer 15

Party wall: Load bearing; sits on property line between 2 buildings
Fire wall: Interior, absolute fire barrier, self supporting, extends from foundation through the roof of the building to a height sufficient to keep the fire from jumping (4hrs)
Fire Partition wall: rating of 3/4 hour, non load bearing, runs from floor to ceiling
Partition wall: non load bearing, used to subdivide large spaces
Parapet wall: Portion of fire or fire partition wall that extends above the roof 18”
Shear Wall: designed to withstand fore of high/shear winds

Question 16

ceilings

Answer 16

Depending on building classification must have a rating of 1,2, or 3 hours

Question 17

7 types of flat roof

+ pitched and curved

Answer 17

Inverted,Rain, wood deck, metal deck, concrete, Poured Gypsum, Mansard

Question 18

4 roof hazards

Answer 18

Skylights
ventilation could sped up collapse
excessive live load
weight of hvac

Question 19

Fire Extension

Answer 19

Fire can travel through connected voids, pipe chases, utility and elevator shafts.

Question 20

Collapse zone and patterns

Answer 20

Zone: 1.5 times building height

Patterns: 
Lean-to
Vee-Shape
A-Frame
Pancake
Cantilever
