Structures are everywhere around us, be it the building keeping us dry from the rain, or the chair keeping us from falling to the ground. Even the cup you drink from is a type of structure! There are three different fundamental types of structures: shell, frame, and solid.
Shell structures are supported by their outer material. These structures are usually hollow inside and require no internal framework to stay upright. An everyday example of this type of structure that we see is the cup we drink water out of.
The frame structure on the other hand needs an internal frame or internal network of beams and pillars to be able to stay upright. It relies on the internal framework to be able to withstand external forces such as wind and rain. One famous example of this is the Eiffel Tower in France. It has a complicated iron lattice framework that has great wind resistance!
Lastly, there is the solid structure. Its name is telling of what kind of structure it is: a structure completely filled and packed on the inside, which provides a strong foundation to withstand anything. A famous example of this is actually one of the seven wonders of the ancient world, the Great Pyramid of Giza.
