The skeleton-&-skin system

2. In the shell system one building material provides both structural support and sheathing (outside covering). Ex. Brick, stone, the log cabin.
The skeleton and skin system is comparable to the human body which has a rigid bony skeleton to support its basic frame and a more fragile skin as sheathing. Ex. Sky scrapers have steel frames (skeletons) supporting the structure and a sheathing of glass or some others light weight material.
“Tensile strength, is the ability of a material to span horizontal distances with minimum support from underneath.”

11. ROUND ARCH AND VAULT ROUND ARCH AND VAULT
The round arch was used by the ancient people Mesopotamia but was fully developed by the Romans, who perfected the form in the 2nd century B.C.E.
The advantages to the arch besides being an attractive form are; it allowed the architect to open up fairly large spaces in a wall without risk, admitted light, reduced the weight of the wall and reduced the amount of material needed. The Romans utilized a perfect semicircle arch. It is constructed from wedge-shaped pieces of stone that meet at an angle always perpendicular to the curve of the arch. The arch is stable only when it is complete, when the topmost stone, the keystone, has been set.
When the arch is extended in depth ---placing many arches flush behind the other it is called a barrel vault.
Groin Vaults- a groin vault results when two barrel vaults are crossed at right angles to each other, directing the weights and stresses to the four corners.

18. The pointed arch
The pointed arch offers many advantages as compared to round arch. Because the sides arch up to a point, weight is channeled down to the ground at a steeper angle as a result the arch can be taller, allowing for more windows and light.
The reinforcements are called ribs.
Gothic builders reinforced theirs walls from the outside with supports called buttresses, piers, and flying buttresses

Purposes of Architecture

23. Dome
A dome is an architectural structure generally in the shape of a hemisphere or half globe.
Another definition of the dome is an arch rotated 360 degrees on its axis.
The stresses in a dome are like those of the arch, except they are spread in a circle around the dome’s perimeter.
Unless the dome is buttressed – supported from the outside – from all sides, there is a chance it
could “explode,” for the stones to pop outward in all directions, causing

31. Corbell Arch and Dome
Islamic architects used a technique called corbelling to create arch and dome like forms. In a corbelled arch, each row of stones extends slightly beyond the one below, until eventually the opening is bridged.

32. CAST IRON CONSTRUCTION
Joseph Paxton, a designer of greenhouses, “Works of the Industry of All Nations” built The Crystal Palace made of cast iron and sheathed in glass. The structure covered more than 17 acres, reached a height of 108 feet and built in sixteen weeks due in large part to prefabrication.
Gustave Eiffel, a French engineer, propose to build in the center of Paris a skeleton iron tower, a thousand feet tall, to act as a centerpiece for the Paris World’s Fair of 1889.

35. BALLON –FRAME CONSTRUCTION
This is a technique for building homes. In 1833, in Chicago, the technique of balloon-frame construction was introduced. Balloon-frame construction is a skeleton-and -skin method that developed from two innovations: improved methods of milling lumber and massed-produced nails.

36. Steel Frame Construction The development of skyscrapers required two innovations: the elevator and steel -frame construction.

39. SUSPENSION
Suspension is the structural method associated with bridges. The concept of suspension was developed for bridges in the 19th century. In essence, the weight of the structure is suspended from steel cables supported on vertical pylons, driven into the ground.

40. Golden Gate Bridge, San Francisco. 1937

41. REINFORCED CONCRETE
In the 19th century a method was developed for reinforcing concrete forms by imbedding iron rods inside the concrete before it hardened. The iron contributes tensile strength, while the concrete provides shape and surface. In the 20th century reinforced concrete, also known as ferroconcrete, is used in a variety of structures

43. GEODESIC DOMES
American architectural engineer R. Buckminster Fuller developed the geodesic dome.
Fuller’s dome is basically a bubble, formed by a system of metal rods arranged in triangles and organized into tetrahedrons. (A tetrahedron is a three-dimensional geometric figure with four faces.
The metal framework can be covered in any of the several lightweight materials, including wood, glass, and plastic

Moshe Safdie designed an experimental apartment duplex called Habitat for the Expo 67, the Montreal World’s fair. The complex consists of 354 prefabricated concrete boxes, stacked on top of another to form 158 apartments.
Frank Lloyd Wright’s approach to homes was characterized by two related principles: first a house should blend with its environment; second, the exterior and interior of a house should be visually and physically integrated. These principles comprised Wright’s theory of “organic architecture”. The Kaufmann House in Bear run, Pennsylvania known as “Falling water” is considered to be his masterpiece.
