Structures, Frames, & Security Introduction to Law, Public Safety, Corrections, and Security

Presentation OverviewDiscuss Framing and Frameworks used Types of structural materials found in buildingsPositives and negatives for each structural materialCosts and additional characteristics for each structural materialRegional availability and popularity for meeting building codes

Building FramesAnessential support structure of abuilding It is the skeleton of a buildingA strong framework is necessary for safe buildings

Different Materials: SteelReinforced Concrete Wood

SteelStrongest of the three materials

High heat tolerance meaning it can withstand high temperatures

High wind tolerance due to the strength of the material

Safest Place to be during disaster: underneath doorways

Reinforced Concrete Reinforced concrete concrete in which wire mesh or steel bars (rebar) are embedded to increase its tensile strength

High heat tolerance

High wind tolerance

Safest place to be during disaster: underneath doorframes

Steel & Reinforced Concrete are usually used for industrial buildings

Wood Weakest material of the three

Low heat tolerance more susceptible to heat

Low wind tolerance more likely to dismantle during high winds

Safest place to be during disaster: Doorways, inside bathtub, not in a wood framed building

Wood frames are used for residential buildings

Exterior Structure Materials Wood SidingSidingConcreteBrickSteel Glass Plastic Stone Stucco

Wood Siding Usually on residential and older buildingsNot very resistant to wind or heatNot a popular choice due to safety hazards Not popular for public buildings due to lack of durability

Siding Aluminum, Reinforced Plaster, ConcreteUsually on newer residential buildingsThere are different types, some stronger than others Less flammable than wood and typically resistant to wind

Concrete Typically used on industrial and public buildingsVery resistant to fire, wind, and gunshots Popular choice for public buildings due to durability and safety

BrickSeen both on residential, industrial, and public buildings. Sometimes seen on older buildings as well. No longer a popular due to expense. It is expensive and not as safe as other equally expensive material.

Steel Seen mostly in industrial or public buildings (such as skyscrapers) High heat and wind toleranceRicochets gunfire Popular choice in cities due to safety and durability

Glass Reinforced glass is typically used in homes and buildings for exterior structures.Still, glass is dangerous. It has a low wind tolerance, a lower heat tolerance, and is prone to shattering. Not a popular choice, and typically only chosen for aesthetics

Stone Stone structures are very strong; some of the oldest buildings in the world are constructed from stone. They have a high wind and heat tolerance Not a popular choice for public buildings due to expense Usually chosen for aesthetics

Plastic Reinforced plastic is both durable and flexibleIt has a high wind tolerance, but a lower heat tolerance This is becoming a popular choice to due lower expense, safety, and durability

Stucco Stucco is a weak material usually seen in residential areasLow heat and wind tolerance In certain areas of the United States (Florida and California) stucco is a popular material of choice due to aesthetics Not a popular choice for public buildings due to lack of safety and durability
