Response
When designing a structure, you must determine the properties
of the structure in order that the structure will support the
loads and perform its intended functions.
e.g. Design of areas for members in simple tension or
compression:
Load to be transmitted
Required area 
Allowable stress
● stiffness—refers to the ability of the structure to resist change
in shape.
● stability—refers to the ability of the structure to resist buckling
under compressive stresses.
● optimization—design the best structure to meet a particular
goal, such as minimum weight.
● load—active forces that are applied to the structure by some
external cause, such as gravity, water pressure, wind, and
earthquake ground motion.
● reaction—passive forces that are induced at the supports of the
structure.
