Column
A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. The term ''column'' applies especially to a large round support (the shaft of the column) with a capital and a base or pedestal, which is made of stone, or appearing to be so. A small wooden or metal support is typically called a '' post''. Supports with a rectangular or other non-round section are usually called '' piers''. For the purpose of wind or earthquake engineering, columns may be designed to resist lateral forces. Other compression members are often termed "columns" because of the similar stress conditions. Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest. In architecture, "column" refers to such a structural element that also has certain proportional and decorative f ...

Ancient Egyptian Architecture
Spanning over three thousand years, ancient Egypt was not one stable civilization but in constant change and upheaval, commonly History of ancient Egypt, split into periods by historians. Likewise, ancient Egyptian architecture is not one style, but a set of styles differing over time but with some commonalities. The best known example of ancient Egyptian architecture are the Egyptian pyramids and Sphinx, while excavated Egyptian temple, temples, palaces, tombs, and fortresses have also been studied. Most buildings were built of locally available mud brick and limestone by paid laborers and craftsmen. Monumental buildings were built using the post and lintel method of construction. Many buildings were Egyptian astronomy, aligned astronomically. Columns were typically adorned with Capital (architecture)#Pre-classical capitals, capitals decorated to resemble plants important to Egyptian civilization, such as the Cyperus papyrus, papyrus plant. Ancient Egyptian architectural motifs ...

Capital (architecture)
In architecture, the capital () or chapiter forms the topmost member of a column (or a pilaster). It mediates between the column and the load thrusting down upon it, broadening the area of the column's supporting surface. The capital, projecting on each side as it rises to support the abacus, joins the usually square abacus and the usually circular shaft of the column. The capital may be convex, as in the Doric order; concave, as in the inverted bell of the Corinthian order; or scrolling out, as in the Ionic order. These form the three principal types on which all capitals in the classical tradition are based. The Composite order was formalized in the 16th century following Roman Imperial examples such as the Arch of Titus in Rome. It adds Ionic volutes to Corinthian acanthus leaves. From the highly visible position it occupies in all colonnaded monumental buildings, the capital is often selected for ornamentation; and is often the clearest indicator of the architec ...

Great Hypostyle Hall
The Great Hypostyle Hall is located within the Karnak Temple Complex, in the Precinct of Amon-Re. It is one of the most visited monuments of Ancient Egypt. The structure was built around the Nineteenth dynasty of Egypt, 19th Egyptian Dynasty (–1224 BC). Its design was initially instituted by Hatshepsut, at the North-west chapel to Amun in the upper terrace of Deir el-Bahri. The name refers to hypostyle architectural pattern. Dedicated to Amun-Re, the highest deity in the Egyptian pantheon, Karnak was once the most opulent religious sanctuary in Thebes, Egypt, Thebes, the imperial capital of Egypt (now Luxor). Architecture and construction The Great Hypostyle Hall covers an area of . The roof, now fallen, was supported by 134 columns in 16 rows; the two middle rows are higher than the others (being in circumference and high). The 134 papyrus columns represent the primeval Cyperus papyrus, papyrus swamp from which Atum, a self-created deity, arose from the waters of Nu (myt ...

Engaged Column
An engaged column is an architectural element in which a column is embedded in a wall and partly projecting from the surface of the wall, which may or may not carry a partial structural load. Sometimes defined as semi- or three-quarter detached, engaged columns are rarely found in classical Greek architecture, and then only in exceptional cases, but in Roman architecture they exist in abundance, most commonly embedded in the cella walls of pseudoperipteral Roman temples and other buildings. In the temples it is attached to the cella walls, repeating the columns of the peristyle, and in the theatres and amphitheatres, where they subdivided the arched openings: in all these cases engaged columns are utilized as a decorative feature, and as a rule the same proportions are maintained as if they had been isolated columns. In Romanesque work the classic proportions were no longer adhered to; the engaged column, attached to the piers, has always a special function to perform, e ...

Structural Engineering
Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and joints' that create the form and shape of human-made Structure#Load-bearing, structures. Structural engineers also must understand and calculate the structural stability, stability, strength, structural rigidity, rigidity and earthquake-susceptibility of built structures for buildings and nonbuilding structures. The structural designs are integrated with those of other designers such as architects and Building services engineering, building services engineer and often supervise the construction of projects by contractors on site. They can also be involved in the design of machinery, medical equipment, and vehicles where structural integrity affects functioning and safety. See glossary of structural engineering. Structural engineering theory is based upon applied physics, physical laws and empirical knowledge of the structural performance of different ...

Colonnade
In classical architecture, a colonnade is a long sequence of columns joined by their entablature, often free-standing, or part of a building. Paired or multiple pairs of columns are normally employed in a colonnade which can be straight or curved. The space enclosed may be covered or open. In St. Peter's Square in Rome, Bernini's great colonnade encloses a vast open elliptical space. When in front of a building, screening the door (Latin ''porta''), it is called a portico. When enclosing an open court, a peristyle. A portico may be more than one rank of columns deep, as at the Pantheon in Rome or the stoae of Ancient Greece. When the intercolumniation is alternately wide and narrow, a colonnade may be termed "araeosystyle" (Gr. αραιος, "widely spaced", and συστυλος, "with columns set close together"), as in the case of the western porch of St Paul's Cathedral St Paul's Cathedral, formally the Cathedral Church of St Paul the Apostle, is an Anglican c ...

Entablature
An entablature (; nativization of Italian , from "in" and "table") is the superstructure of moldings and bands which lies horizontally above columns, resting on their capitals. Entablatures are major elements of classical architecture, and are commonly divided into the architrave (the supporting member immediately above; equivalent to the lintel in post and lintel construction), the frieze (an unmolded strip that may or may not be ornamented), and the cornice (the projecting member below the pediment). The Greek and Roman temples are believed to be based on wooden structures, the design transition from wooden to stone structures being called petrification. Overview The structure of an entablature varies with the orders of architecture. In each order, the proportions of the subdivisions (architrave, frieze, cornice) are defined by the proportions of the column. In Roman and Renaissance interpretations, it is usually approximately a quarter of the height of the column. Va ...

Pedestal
A pedestal or plinth is a support at the bottom of a statue, vase, column, or certain altars. Smaller pedestals, especially if round in shape, may be called socles. In civil engineering, it is also called ''basement''. The minimum height of the plinth is usually kept as 45 cm (for buildings). It transmits loads from superstructure to the substructure and acts as the retaining wall for the filling inside the plinth or raised floor. In sculpting, the terms base, plinth, and pedestal are defined according to their subtle differences. A base is defined as a large mass that supports the sculpture from below. A plinth is defined as a flat and planar support which separates the sculpture from the environment. A pedestal, on the other hand, is defined as a shaft-like form that raises the sculpture and separates it from the base. An elevated pedestal or plinth that bears a statue, and which is raised from the substructure supporting it (typically roofs or corniches), is some ...

Compression Member
A compression member is a structural element that primarily resists forces, which act to shorten or compress the member along its length. Commonly found in engineering and architectural structures, such as columns, struts, and braces, compression members are designed to withstand loads that push or press on them without buckling or failing. The behavior and strength of a compression member depends on factors like material properties, cross-sectional shape, length, and the type of loading applied. These components are critical in frameworks like bridges, buildings, and towers, where they provide stability and support against vertical and lateral forces. In buildings, posts and columns are almost always compression members, as are the ''top chord'' of trusses in bridges, etc. Design For a compression member, such as a column, the principal stress primarily arises from axial forces, which act along a single axis, typically through the centroid of the member cross section. As detail ...

Post (structural)
A post is a main vertical or leaning support in a structure similar to a column or pillar, the term post generally refers to a timber but may be metal or stone. A stud in wooden or metal building construction is similar but lighter duty than a post and a strut may be similar to a stud or act as a brace. In the U.K. a strut may be very similar to a post but not carry a beam. In wood construction posts normally land on a sill, but in rare types of buildings the post may continue through to the foundation called an interrupted sill or into the ground called earthfast, post in ground, or posthole construction. A post is also a fundamental element in a fence. The terms "jack" and "cripple" are used with shortened studs and rafters but not posts, except in the specialized vocabulary of shoring. Timber framing Timber framing is a general term for building with wooden posts and beams. The term post is the namesake of other general names for timber framing such as post-and-beam, post- ...

Egyptian Hieroglyphs
Ancient Egyptian hieroglyphs ( ) were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined Ideogram, ideographic, logographic, syllabic and alphabetic elements, with more than 1,000 distinct characters.In total, there were about 1,000 graphemes in use during the Old Kingdom period; this number decreased to 750–850 during the Middle Kingdom, but rose instead to around 5,000 signs during the Ptolemaic period. Antonio Loprieno, ''Ancient Egyptian: A Linguistic Introduction'' (Cambridge: Cambridge UP, 1995), p. 12. Cursive hieroglyphs were used for Ancient Egyptian literature, religious literature on papyrus and wood. The later hieratic and demotic (Egyptian), demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Egyptian hieroglyphs are the ultimate ancestor of the Phoenician alphabet, the first widely adopted phonetic writing system. Moreov ...

Beam (structure)
A beam is a structural element that primarily resists loads applied laterally across the beam's axis (an element designed to carry a load pushing parallel to its axis would be a strut or column). Its mode of deflection is primarily by bending, as loads produce reaction forces at the beam's support points and internal bending moments, shear, stresses, strains, and deflections. Beams are characterized by their manner of support, profile (shape of cross-section), equilibrium conditions, length, and material. Beams are traditionally descriptions of building or civil engineering structural elements, where the beams are horizontal and carry vertical loads. However, any structure may contain beams, such as automobile frames, aircraft components, machine frames, and other mechanical or structural systems. Any structural element, in any orientation, that primarily resists loads applied laterally across the element's axis is a beam. Overview Historically a beam is a squared ti ...
