Architectural Characteristics 1. Courtyard and Sky wells a. Open courtyard - A large empty space surrounded by buildings connected with one another either directly or through verandas - More common in northern Chinese architecture b. "Sky well" - A relatively small enclosed courtyard which offer small opening to the sky through the roof space from the floor up - More common in southern China 2. Hierarchical - importance and uses of buildings are based on the strict placement of buildings in a property/complex a. Orientation of Doors - Facing the front (important) - Facing the sides (less important) - Facing the rear (least important) b. Location of Buildings - At the back of properties are more important : a. Elder members of the family b. Celebratory rites c. Ancestral plaques - In front of the property: typically for servants and kitchen c. Courtyard Location - central courtyard are more important than peripheral ones 3. Horizontal Emphasis - Emphasis on the breadth and less on height with close heavy platform and a large roof that floats over this base with vertical walls not well emphasized - Stresses the visual impact of the width of the buildings to denote the all-embracing nature of imperial China 4. Mythical Concepts - Feng shui and mythic elements in the construction and layout of Chinese architecture. This includes the use of: a. Screen walls to face the main entrance of the house, which stems from the belief that evil things travel on straight lines b. Talismans and fortuitous imagery: 1) Door gods on doorways to ward evil and encourage the flow of good fortune 2) Fu Lu Shou - Taoist concept which denotes the attributes of the good life: good fortune, prosperity and longevity Craft: Techniques & Materials 1. Jian - "Bay" - The interval/ space between four columns and is the basic module of a Chinese dwelling - This space is both a two-dimensional floor space and is also a volumetric measure of the void defined by the floor, the columns, and the beams set across the columns - More than a structural unit, this type of measurement is used by carpenters as a design module to be duplicated in series to form the overall layout at ground level and on the floor above - This ultimately regulates the overall size of common dwellings and fashions their visual proportions - The use of this structural unit enforces a discipline, an order, on the building, standardizing the timber construction members and facilitating their assembly 4 Chinese Architecture Page 1 2. Foundations - Following building traditions, reaching back at least as far as the Shang dynasty, a tamped earth foundation or podium at ground level or slightly elevated is considered the necessary base - A dry tamped foundation can be achieved using troughs and sometimes underground conduits to drain water - Stone foundation or wall footings are commonly laid along tamped perimeter of Chinese dwelling/structures in an effort to reduce the absorption of soil moisture by the walls 3. Chinese Building Fundamentals - Chinese builders span and enclose space using a variety of building solutions to collect the forces of gravity and transmit them to the ground a. Load-bearing walls Directly carries the weight of the roof and/or upper stories b. Wooden structural frameworks Sustain the load of upper storeys and the roof independently of the walls Utilize freestanding lightweight interior walls separate from the load-bearing columns 4. Walls - Can be either: a. Load-bearing Walls which directly support the roof structure, often thick with few breaks for windows or doors b. Non load-bearing Walls that encircle the wooden structural framework or placed between pillars - Common materials used: Tamped earth or a composite material ► "hangtu" - method of constructing solid walls involving piling freshly dug earth into a slightly battered caisson or box frame Adobe ► Permits greater variations in construction form ► Widely used by poorer peasants Kiln-dried brick ► Walls made up of this material usually have larger and more numerous openings for windows and doors Vegetable origin ► Use of bamboo, kaoliang or cornstalks to form a curtain wall that bears no load from above Wood, Grasses Stone Wooden structural framework Bamboo matting Wattle Daub ► used to form the curtained enclosure 5. Wooden Structural Frameworks - Framing systems: a. Pillars and Beams (tailang or liangzhu) Also known as post and lintel Simplest A pair of pillars supporting a horizontal beam upon which are set short vertical posts or struts to lift another beam, upon which is fitted another strut, and on these are fitted five purlins which define the slope of the roof and across which the roof rafters are laid b. Pillars and Transverse tie beams (chuandou) Differs from other framing system in three important manner: i) The roof purlins which support the rafters and roof itself rest directly on notched pillars rather than on beams or struts ii) The number of pillars is greater iii) Horizontal tie beam members are mortised directly into or tenoned through the multiple pillars to form an interlocked matrix that inhibits skewing of the frame 4 Chinese Architecture Page 2 Construction System 1. Dougong Brackets - Structural system of brackets found between the top of a column and a cross beam - Each is formed of a double bow-shaped arm (gong) which supports a block of wood (dou) on each side - Fixed layer upon layer, the arrangements bear the load of the roof - Highly resistant to earthquakes Roof Craft: Techniques and Materials 1. Firm mountain(Yingshan ding) □ Most common roof profile 2. Overhanging gable (Xuanshan ding) □ Combined with the use of overhanging eaves on the facade to offer a degree of protection from both rain and sun 3. Horse's head walls(matou qiang) □ Orignated as fire walls to retard the spread of sweeping roof fires in adjacent dwellings, temples, clan halls and other buildings in towns and nucleated villages Construction System Three main types: 1. Straight inclined □ Roofs with a single incline □ Prevalent in commoner architectures 2. Multi-inclined □ Roofs with two or more sections of incline □ Used in higher class constructions, from the dwellings of wealthy commoner to palaces 3. Sweeping □ Roofs with a sweeping curvature that rises at the corners of the roof □ Reserved for temples and palaces although it may also be found in the homes of the wealthy Building Types Commoners 1. Tulou □ "earth dwelling" □ "round stronghouse" □ A large, enclosed and fortified earth building with very thick load-bearing rammed earth walls □ Smaller interior buildings contain halls, storehouses, wells and living areas □ Well-ventilated, windproof and earthquake- proof □ Has only one main gate, guarded by 4-5 inch thick wooden doors reinforced with an outer shell of iron plate □ Top level of these earth buildings has gun holes for defensive purposes 4 Chinese Architecture Page 3 4 Chinese Architecture Page 4 2. Siheyuan 1 Main entrance 2 Rooms facing the rear 3 First courtyard for cooking Second courtyard was a living space 4 Rooms for the sons and daughters 5 Inner Hall for greeting guests and family ceremonies 6 Main building Living space for parents 7 Small side rooms Used for children and extended family members Parts of a Chinese Dwelling Symbol and Tradition Wuji Ridge roof Jia - Chinese word for both home the dwelling, Chuanzi Rafter and family related members of the Jilin Ridge pole household who occupies it - Shelters the household, providing it with a Lin Purlins haven from the changing forces of nature Liang Main beam - A dwelling is symbolic of family unity and Shan qiang Gable wall sanctuary - A public statement of status as well as a Zhuzi Pillar/ post tangible expression of the family's aspiration Chuanggezi Lattice window - Is it a dynamic entity that expresses in Chuang-hu Solid window varying degrees the changing relationships within the family Chuang tai Window sill - Symbolizing and accommodating evolving Qiang Wall hierarchical patterns - Taijie Steps In the organization of the layout of a Chinese dwelling and/or structure, the individual is Menken Threshold essentially disregarded with space defined Menkuang Door frame more broadly in terms of family rather than personal needs and use Men Door Menmei Lintel Yan Eaves 4 Chinese Architecture Page 5 Imperial - Palaces Architectural features that were reserved solely for buildings built for the Emperor of China 1. Color coding - Yello w roof tiles - Red wooden columns and wall surfaces - Black often used in pagodas . They believe the gods are inspired by the black color to descend on to the earth 2. Dougong brackets - A feature shared only with the largest of religious buildings 3. Five-clawed dragon - Adopted by the first Ming emperor for his personal use - Used as decoration on the beams, pillars and on the doors 4. Nine jian - Jian: Space between two columns 5. Five arches - Only the gates used by the Emperor could have five arches - Center arch reserved for the Emperor himself 6. Orientation - Buildings faced the south because the north had a cold wind - Important of the east (direction of the rising sun) in orienting and siting Imperial buildings is a form of solar worship 7. Numerology - Heavily influenced Imperial architecture - Hence the use of nine in much of construction, as nine being the greatest single digit number The Forbidden City - Built in 1406 to 1420 - Consists of 980 surviving buildings - 8, 707 bays of rooms - 720 000 square meters - Declared a world heritage site in 1987 - Largest collection of preserved ancient wooden structures in the world Tiananmen Square - Extensive open area in central Beijing, China - World's largest public square - Adjacent to Forbidden City - Site of festivals, rallies and demonstrations - In 1989, Chinese troops fired on an estimated 2 000+ student demonstrators:( Gate of Heavenly Peace - Famous monument in Beijing - Widely used as a national symbol 4 Chinese Architecture Page 6 Religious 1.
