Structure

STRUCTURES: Structure and form are part of the constant communication between the human and the environment. Structure is something that has a definite size and shape.

Permanent: buildings, damns, bridges… Temporary: used in ephemeral situations. · Types:

Arch and keystone: made from wedge shaped peaces

Dome: made from equal arches that span around a circle. Barrel vault: tunnel made from a series of arches. · Basic structural elements:

The simplest elements that you can find in a structure, are those that are molded as two lines.

Pole: (Column), beam

Principal structural systems: a structure is usually formed by an array of basic elements.

Most important structural characteristics are resistance, stiffness and ductility.

Is important to remember that virtually, all structural systems are three-dimensional, and its decomposition into subsystems planes tends to ignore the interaction between them and the behavior of all of them.
