Structure



An architectural structure is a free-standing, immobile outdoor construction. The structure may be permanent. Typical examples include buildings and nonbuilding structures such as bridges, dams, electricity pylons, and radio masts. Some structures are temporary, built for ephemeral events such as trade shows, conferences or theatre, and often dismantled after use. Temporary structures have fewer constraints relating to future use and durability, and often comprise lightweight forms such as tents, which are quicker to erect, take down, and re-use.

Types of structures

 * Post and lintel** is a simple construction technique, also called "post and beam", where a horizontal member (the lintel or header) is supported by two vertical posts at either end. This very simple form is commonly used to support the weight of the structure located above the openings in a bearing wall created by windows and doors.

A **rafter** **or beam** is one of a series of sloped structural members that extend from the ridge or hip to the down slope perimeter or eave, designed to support the roof deck and its associated loads.




 * “Truss”:** is a structure comprising one or more triangular units constructed with straight slender members whose[[image:Imagen7.png width="119" height="183" align="right"]] ends are connected at joints referred to as nodes.

**“Pinned Frame”:** A piece of wood frames the structure that helps to liberate the tension


 * Portal frame** construction is a method of building and designing simple structures, primarily using steel or steel-reinforced precast concrete although they can also be constructed using laminated timber such as “glulam” (Glued laminated timber**)**[[image:Imagen10.jpg width="177" height="141" align="right"]]

**Arch** is a structure that spans a space while supporting weight.


 * Dome** is a structural element of architecture that resembles the hollow upper half of a sphere.

A structure is a fundamental and sometimes intangible notion covering the recognition, observation, nature, and stability of patterns and relationships of entities.
