Structural System
A structural system can be defined as a stable assembly of
elements designed and constructed to function as a whole in
supporting and transmitting applied loads safely to the ground
without exceeding the allowable stresses in the members.

cables
A thin tensile member that is unable to
resist compression or bending; pure
tension
Arches
A usually curved structure forming the upper edge of an
open space and supporting the weight above it, as in a
bridge or doorway. A structure, such as a freestanding
monument, shaped like an inverted U. A curve with the
ends down and the middle up
Rigid arch
allows no rotation at end supports
hinged arch
used to control bending due to deflection
Columns
A linear (typically vertical)
structural member that is loaded
with compressive forces along its
axis
Short column
subject to excessive loading fails by crushing
long column
subject to increasing compressive loading which will suddenly buckle
Beams
linear structural member with loading applied
perpendicular to its long axis, such a load is a bending load
Bending
tendency of a member to bow as a result of loads applied perpendicular to its longest axis
continuous beam
spans over several supports
joists beam
closely spaced beams spanning in a single direction
beam grid
system of beams that span in two directions joined to each other
trusses
A triangulated assembly that distributes loads to
supports through a combination of pin-connected
members arranged in triangles so that ideally all are
in either pure compression or tension (no bending
or shear) and all thrust forces are resolved
internally
