Types of Structures
Anything that is built or constructed to support a load.
What is a structure?
Forces that act within a structure.
Internal Forces
Any weight or force that a structure must support.
Load
Occurs when a structure can no longer support the loads it was designed for.
Structural Failure
Name the two main types of structures.
Natural and Manmade
Forces that act on a structure from outside.
External Forces
Two types of loads.
Dynamic and Static
Overloading or poor design
This structure is made from a network of smaller parts or materials. An example is a house.
Frame structure
Wind or an Earthquake
External Forces
This type of load is a temporary load that can change, such as cars driving over a bridge.
A dynamic load
Give a real-life example of structural failure.
Tacoma Narrows Bridge, Quebec Bridge, etc.
This type of structure is made from strong materials that can withstand. An example is a rock.
Solid Structure
A pulling force that can stretch materials.
Tension
This type of load, such as the weight of the structure itself.
Static load
This is the second most common cause of structural failure.
Faulty Construction
This type of structure is a hollow structure that is strong and lightweight. An example is an egg.
Shell Structure
The action of twisting of the state of being twisted, especially of one end of an object relative to the other.
Torsion
Explain how loads can affect structural design.
Loads determine the materials and shapes used in a structure to ensure it can safely support the weight and forces it will encounter.
The failure of a structure's base.
Foundational Failure
