Q

According to Vitruvius

A

Architecture is an imitation of nature and a structure must exhibit 3 qualities

Firmitas = strength/durability 
Utilitas = utility 
Venutas = beauty

Q

Pier Luigi Nervi (1891-1979)

A

Italian engineer and architect
Developed new idea of using reinforced concrete
Developed new materials: ferrocemento

Believed that:
Engineering and architecture were two connected parts of a whole
A designer needs three ingredients to develop ingenious solutions:
-a thorough understanding of the laws of physics and materials
-a good interpretation of the essential factors of each problem
-an open mind - overcoming the limitations of the solutions of the past

  • tensile

Q

Post and lintel (column and beam)

A

Post - vertical structural member (column)
Lintel - a horizontal structure that spans on opening (beam)
Trabeated system - based on horizontal beams supported by vertical columns
Most commonly used in : Neolithic, Ancient Greek, ancient Egyptian, Persian, Indian, Chinese, Japanese, and South American architecture
Disadvantage- limited weight can be held up, small distances required between the posts

Note: under stress, lintel bends and the upper half is in compression, lower half is in tension
Therefore, materials for lintel should be strong in both tension and compression

Q

Corbel and cantilever

A

Corbel - masonry that projects slightly from a wall and acts as a support
Corbeled arch - construction, without true arching action, made by shifting opposing courses slightly and regularly inward until they meet
Corbelled dome - made up of rigs of stones or wood, with each successive ring smaller and slightly projecting beyond the one below it

Cantilever - a beam or beams firmly anchored at one end and unsupported at the other end
Below a roof = eave
Overhanging second floor = jetty

Q

Arch and vault

A

Voussoir - wedge-shaped stones
Centering - temporary framework

Most important types of arches

  • semicircular (roman)
  • pointed
  • horseshoe
  • segmental
  • corbeled
  • Tudor

Note: the steeper the arch or the dome the less the lateral thrust

Q

Truss and space frame

A

Truss- a structural frame composed of relatively short elements, typically configured in triangles, used to form a bridge or span a roof

Romans - first used the system for wooden bridges
Medieval period - used to support church roofs
19th century - bridge builders reinvent trusses and use them in various triangulated configurations - used wood, iron, steel
Warren truss - probably most common today

Note: a truss bridge is economical to construct because of its efficient use of materials

Space frame - a truss repeated in 3 dimensions
It is useful for long clear-span roofs

17
Q

Tensile

A

Tensile structures- is a construction of elements carrying only tension and no compression or bending (fabric tents w/upright posts, suspension bridges)
Ex. Sidney Myer music bowl in Melbourne Australia - 1958

Note: most often used as roofs because they can economically and attractively span large distances

18
Q

Conclusion

A

The selection of any of the systems for a building depends on:

Economics
Client and architect esthetic preference
Spatial requirements
Material availability

19
Q

Architectural styles

A

The dome of the US capitol

20
Q

Orthographic projection

A

Is a way of representing a 3D object in 2D

21
Q

Plan

A

Represents the view of a building as seen from above once a horizontal cutting plan has been passed through it, usually above the height of the window sills, with the top part removed

22
Q

Elevation

A

The view obtained by projecting the imagine of a building on a vertical cutting plane passing through the ground a few feet away in front of one exterior face of a building

23
Q

Section

A

The view obtained by projecting the imagine of a building on a vertical cutting plane passing through the ground, inside of a building

24
Q

Perspective drawing

A

Shows all 3 dimensions through foreshortening, as photography does
Distorts the size of the elements that are further away, they are smaller in size
It resembles a photograph

Easy to understand
Communicates appearances of the designed structures to the big public

25
Q

Axonometric drawing

A

It also shows all 3 dimensions but without distorting these dimensions
It distorts some of the angles

26
Q

Timeline

A

Prehistoric architecture - origins of human life traced to central Africa (or perhaps Central Europe based on new archeological findings) approximately 5 million years ago

Terra Amata, near Nice, France - 400,000-300,000 BC : one of the sites of earliest surviving evidence of prehistoric House. Believed to be temporary shelters for a hunting/ gathering season

Cages at Lascaux, France - 15,000-13,000 BC : prehistoric ritual site. Multicolored paintings on walls of animals, humans, tools, and hunting rituals. Evidence of the importance of ritual in prehistoric times - the Hall of the Bull

Catal Huyuk, Anatolia (Turkey) , 6500 BC : permanent housing settlement. One of the first urban settlements. Evidence of religious or ritual figures and statutes

27
Q

Timeline continued

A

Carnac, France - 4,500 BC : organizes arrangement of megaliths. Possible ritual site.

Newgrange passive grave, county Meath, Ireland, ca. 3100 BCE : ancient stone burial site

Stonehenge, Salisbury plain, England- 2950-1700 BC : intricate composition of megaliths arranged in various combinations and orientations. Believed to be a astronomical and or ritual site

Skara Brae, Scotland - 2500-1500 BC : stone housing settlement

Biskupin, Poland -1000-1500 BC
wood housing settlement/village on an island. Discovered in 20th century, had been submerged under water which allowed it to be preserved
