Definition Slide Structure - an arrangement of parts
Solid Structures • Coral – Coral is a structure built by millions of organisms. It is essentially a solid structure with no space enclosed by the material from which it is built. • Stone fence – These stones are arranged into a structure that serves the function of defining a property line and setting up a barrier. The wall is solid, and it is the weight of the stones themselves that provide strength and stability to the wall.
Solid Structures • Fanshawe Dam – A dam is basically a solid mass structure. Although there may be a small control room enclosed inside, the walls are very thick in proportion to the space inside. • Statue – The statue is made from material poured into a mold and is solid.
Frame Structures • Skeleton – The skeleton of any animal provides support for the body. The skin provides a cover, but it is the bones of the skeleton that support the weight of the animal. • New house – In this house under construction, the wooden framework is clearly visible. It rests on a cement block foundation. Drywall will be attached to the framing to enclose spaces. The wall joists and roof trusses support all of the weight of the building.
Frame Structures • Soccer net – The soccer net is a simple frame structure. • Hydro tower – The steel framework of the Hydro tower supports the weight of the structure. • Skyscraper – Reinforced concrete beams and columns provide the structure of the skyscrapers. The weight of the outer shell of concrete and glass hangs on this framework.
Shell Structures • Lobster – The shell of the lobster is made of a hard, rigid material containing calcium. For any animal that has an exoskeleton, it is the outer shell that supports the animal. • This stove has a shell of sheet metal. • Water tower – The sphere at the top of the water tower does not contain an internal framework.
Shell Structures • Victoria Park Bandshell – Most of the weight of the structure is found in the shell. • Aquatic Centre – The corrugated steel shell is very rigid and creates a structure which contains a large open space. • Computer case – The rigid plastic/metal of the case of this computer is sufficiently strong to protect the internal parts.
