Reciprocal Frame
A reciprocal frame is a class of self-supporting structure made of three or more beams and which requires no center support to create roofs, bridges or similar structures. Construction Reciprocal roofs tend to be constructed in one of two ways. If built using dimensioned timber, each rafter is usually jointed into the previous one. More commonly, these roofs are constructed with roundwood poles where each rafter is laid upon the previous one. In both of these approaches, the roof is assembled by installing a temporary central support that holds the first rafter at the correct height. The first rafter is fitted between the wall and the temporary central support and then further rafters are added, each resting on the last. The final rafter fits on top of the previous rafter and under the very first one. The rafters are then tied before the temporary support is removed. The structure is most effective at lower pitches where there is minimal spreading force exerted at the ringbeam, mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three Stick Reciprocal Frame
3 (three) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic numerals, Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. ...

Mandala
A mandala (, ) is a geometric configuration of symbols. In various spiritual traditions, mandalas may be employed for focusing attention of practitioners and adepts, as a spiritual guidance tool, for establishing a sacred space and as an aid to meditation and trance induction. In the Eastern religions of Hinduism, Buddhism, Jainism and Shinto it is used as a map representing deities, or especially in the case of Shinto, paradises, kami or actual shrines. Hinduism In Hinduism, a basic mandala, also called a '' yantra'', takes the form of a square with four gates containing a circle with a centre point. Each gate is in the general shape of a T. Mandalas often have radial balance. A '' yantra'' is similar to a mandala, usually smaller and using a more limited colour palette. It may be a two- or three-dimensional geometric composition used in '' sadhanas'', puja or meditative rituals, and may incorporate a mantra into its design. It is considered to represent the abode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Villard De Honnecourt
Villard de Honnecourt (''Wilars dehonecort'', ''Vilars de Honecourt'') was a 13th-century artist from Picardy in northern France. He is known to history only through a surviving portfolio or "sketchbook" containing about 250 drawings and designs of a wide variety of subjects. Life Nothing is known of Villard apart from what can be gleaned from his surviving "sketchbook." Based on the large number of architectural designs in the portfolio, it was traditionally thought that Villard was a successful, professional, itinerant architect and engineer. This view is sometimes contested today, as there is no evidence of him ever working as an architect and the drawings contain some inaccuracies. However, Honnecourt compiled a manual that gave precise instructions for executing specific objects with explanatory drawings. In his writings he fused principles passed on from ancient geometry, medieval studio techniques, and contemporary practices. The author includes sections on technical pro ...

Structural System
The term structural system or structural frame in structural engineering refers to the load-resisting sub-system of a building or object. The structural system transfers loads through interconnected elements or members. Commonly used structures can be classified into five major categories, depending on the type of primary stress that may arise in the members of the structures under major design loads. However any two or more of the basic structural types described in the following may be combined in a single structure, such as a building or a bridge in order to meet the structure's functional requirements.Kassimali, A. (1999). ''Structural analysis''. 2nd edition. Pacific Grove, C.A.: PWS Publication. * Tensile structures: Members of tensile structures are subject to pure tension under the action of external loads. Because the tensile stress is uniformly distributed over the cross-sectional area of members, the material of such a structure is utilized in the most efficient ...
