Truss

In architecture and structural engineering, a truss is a structure consisting of straight slender members connected at joints.

In order for a truss to be rigid, it must be composed entirely of triangles.

In mathematical terms,

we have the following condition for its proper stability (the truss will not collapse):

where m is the total number of truss members and j is the total number of joints.

Architecture: Architecture (in Greek αρχή = first and τέχνη = craftsmanship) is the art and science of designing buildings and structures. A wider definition would include within its scope the design of the total built environment, from the macrolevel of town planning,...

Structural engineering: Structural engineering is the field of civil engineering particularly concerned with the design of load-bearing structures. In practice, it is largely the implementation of mechanics to the design of structures, such as buildings, bridges, walls (including retaining walls), dams, tunnels, etc....
