Discuss Framing and Frameworks used Types of structural materials found in buildings Positives and negatives for each structural material Costs and additional characteristics for each structural material Regional availability and popularity for meeting building codes

An essential support structure of a building It is the “skeleton” of a building A strong framework is necessary for safe buildings Different Materials: Different Materials: Steel Reinforced Concrete Wood

Strongest 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 – 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

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

Wood Siding Siding Concrete Brick Steel Glass Plastic Stone Stucco

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

Usually on newer residential buildings There are different types, some stronger than others Less flammable than wood and typically resistant to wind

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

Seen 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.

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

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 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

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

Stucco is a weak material usually seen in residential areas Low 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
