Assignment 5

Architecture 


Post and lintel -The simplest illustration of load and support in construction; in which two upright members (posts, columns, piers) hold up a third member (lintel, beam, girder, rafter) laid horizontally across their top surfaces. This is the basis for the evolution of all openings. But, in its pure form, the post-and-lintel is seen only in colonnades and in framed structures, since the posts of doors, windows, ceilings, and roofs are part of the wall. 

Coliseum, Rome

Coffers - a sunken panel in the shape of a square, rectangle, or octagon in a ceiling or vault. A series of these sunken panels were used as decoration for a ceiling or a vault, also called caissons, or lacunaria, while a coffered ceiling was sometime called a lacunar. 

Pantheon, Rome

Arch (round and pointed) - a curved structure that supports the weight of material over an open space, as in a bridge or doorway. 

Notre Dame, Paris


Pediment - a element consisting of the triangular section found above the horizontal structure, typically supported by columns. 

Louvre, Paris


 Baroque facade - exterior face of a building; new emphasis was placed on bold massing, collanades, domes, light-and-shade, 'painterly' color effects, and the bold play of volume and void. 

  

St. Peter’s Bascilica, Rome


Dome - a roof form which is usually hemispherical and constructed over a circular, square, or octagonal space in a building.

Duomo, Florence


Oculus - “eye” name of the round opening in the top of the dome and in reference to other round windows and openings.

Pantheon, Rome


Barrel vault - a tunnel vault or a wagon 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. 


Notre Dame, Paris


Stained Glass Windows

Notre Dame, Paris


Steel Construction


Eiffel Tower, Paris


Three Orders of Column

o   Doric -  It is the simplest of the orders, characterized by short, faceted, heavy columns with plain, round capitols (tops) and no base.

o   Ionic - It is distinguished by slender, fluted pillars with a large base and two opposed volutes (also called scrolls) in the echinus of the capital

o   Coninthian - the most ornate of the Greek orders, characterized by a slender fluted column having an ornate capital decorated with two rows of acanthus leaves and four scrolls. It is commonly regarded as the most elegant of the three orders
