Kinds of structures
Shell structures
Shell structures are made of a thin outer layer of material around a volume. That volume can be empty space or contain something with no structural relevance.

Arch
The romans were the inventors of the original arch (which derivated to triangular arch, equilateral arch, horseshoe arch, etc)
In Roman times, arches were made of stones. The stone at the
very top is called the “keystone”.
The geometry of the arch displaces the forces to the sides, so that
there is a large free space under the arch.
Mix and Match
It is as simple as mixing different kinds of structures to make a more complex structure even sometimes defying what we thought was possible to build.
Mass structures
-
The good part about this technique is that the structure stands by it´s own weight, even though it´s a shame that it takes lots of space and needs of a lot of material.
Suspension structures
A suspension structure holds an element
(often a beam) by cables that are held from the top of a tall column.
-
Even though it is pretty good for covering large spans, it´s pretty expensive to build.
