General Structure Knowledge
Something with a definite size, shape, purpose and can hold a load
A structure
This structure has an outside layer to provide support/ holds everything together
shell structure
A push or a pull (can make an object stop moving)
a force
the weight or source of pressure that creates an external force on a structure
load
the study of how furniture/structure/etc. can be arranged to allow people to work comfortably and efficiently
ergonomics
Trees, beaver dams, birds nests
Natural structures
this structure relies on a 3D framework with parts that are connected together
frame structure
the force that is applied to everything on earth
gravity
a load that does not change (ex: a parked car)
static load
when an object is the same on both sides to create balance and harmony
symmetry
the shape, size, and materials of a structure
form
Also referred to as a mass structure (one piece of material)
solid structure
a force that acts on a structure from outside the structure
external force
a force that can change when acting on a structure (ex: snowfall)
dynamic force
A large building collapses, what are 3 possible explanations for why this occurres?
EX: design failure, poor foundation, unanticipated forces
A structure's purpose or ability to do something
function
A crane
frame structure
a force that acts from within a structure
internal force
A bridge that uses a semi-circular shape to support the load
arch bridge
a word used to describe the visual appeal of something
aesthetics
the principle stating that the shape of a structure should relate to its function or purpose
"form follows function"
An anchor
solid structure
4 types of internal forces
compression, tension, shear, torsion
4 kinds of bridges
beam, truss, arch, suspension
A measure of the intensity of a force
magnitude
