Load bearing Architecture

Crenellations: crenellation - a rampart built around the top of a castle with regular gaps for firing arrows or guns

Post and lintel is a simple construction method using a lintel, header, or architrave as the horizontal member over a building void supported at its ends by two vertical columns, pillars, or posts and has been used for centuries.

A corbel arch is an arch-like construction method that uses the architectural technique of corbeling to span a space or void in a structure, such as an entrance way in a wall or as the span of a bridge.

A barrel vault is an architectural element formed by the extrusion of a single curve (or pair of curves, in the case of a pointed barrel vault) along a given distance. The curves are typically circular in shape, lending a semi-cylindrical appearance to the total design.

An arch is a structure that spans a space and supports a load and appeared as early as the 2nd millennium BC in Mesopotamian brick architecture.

A groin vault (also known as

a double barrel vault or cross vault) is produced by the intersection at right angles of two barrel vaults. The word groin refers to the edge between the intersecting

vaults; cf. ribbed vault.

Pointed arch with keystone is the central wedge-shaped stone of an arch that locks its parts together. Also called headstone.

The Islamic arch curves upward and inward, but ends in a point.

An onion dome is a dome whose shape resembles an onion, after which they are named. Such domes are often larger in diameter than the drum upon which they are set, and their height usually exceeds their width. These bulbous structures taper smoothly to a point.

Round arches were first used in ancient Babylon and later became a favorite in Roman construction.

Balloon framing is a method of wood construction used primarily in Scandinavia, Canada and the United States (up until the mid-1950s), utilizing a long continuous framing members (studs) that run from the sill plate to the top plate, with intermediate floor structures let into and nailed to them

A geodesic dome is a spherical or partial-spherical shell structure or lattice shell based on a network of great circles (geodesics) on the surface of a sphere. The geodesics intersect to form triangular elements that have local triangular rigidity and also distribute the stress across the structure.

Steel frame usually refers to a building technique with a "skeleton frame" of vertical steel columns and horizontal I-beams, constructed in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The development of this technique made the construction of the skyscraper possible.

Three ancient orders of architecture—the Doric, Ionic, and Corinthian—originated in Greece, each distinguished by its proportions and characteristic profiles and details, and most readily recognizable by the type of column employed.

Doric

Corinthian

Ionic
