Our editors will review what you’ve submitted and determine whether to revise the article.\r\n Access the world’s original book of answers. The post and lintel were not fundamentally altered until the production of cast-iron columns, which were stronger yet smaller in circumference, thus greatly reducing the mass and weight of buildings. Post material must be especially strong in compression.
Limited weight, small spanning distances, weak or "breaking" point. Masonry lintels, depending on the cohesiveness of mortar, are especially weak; therefore, in masonry construction, lintels of monolithic (single slab) stone, wood, and stronger materials are used. In architecture, post and lintel (also called prop and lintel or a trabeated system) is a building system where strong horizontal elements are held up by strong vertical elements with large spaces between them. Much construction in modern materials is based on the post-and-lintel system of the past. Post and Lintel construction of Stonehenge Theories of Stonehenge By: Brandon Hawryluk - It is believed around 250bc a group of druids used Stonehenge for rituals -lately Stonehenge has thought to been used to predict when events in space would occur like the summer solstice The use … Our three-volume, first edition book is now available online through your Britannica Premium membership.\r\n Supports the weight of the structure located above.
This is the basis for the evolution of all openings.
Today, most post and lintel construction has a third component---the wall---which adds additional support and hides the post and lintel design within the framework. The “mushroom” column is a further departure, since the unit can be extended into a covering slab and becomes a ceiling as well as a support.The size of arches is limited only by economy; large arches exert large thrusts, and they are hard to buttress and to build. Drainage and water collection system. The posts must support the lintel and its loads without crushing or buckling. Post-and-Lintel Construction. Stonehenge: use of Post and Lintel. This construction technique was used at Stonehenge, estimated to have been constructed in 2,800 BC. Steel and concrete skeletons restore to modern architecture the formal simplicity of the oldest structures known. The original concept, however, of the duality of post and lintel has been abandoned and post-and-lintel has become a unit with the stresses distributed throughout.Our editors will review what you’ve submitted and determine whether to revise the article.\r\n Access the world’s original book of answers.
The form may be varied to meet specific problems; the most efficient forms in masonry are semicircular, segmental (segment of a circle), and pointed (two intersecting arcs of a circle), but noncircular curves can be used successfully. Our three-volume, first edition book is now available online through your Britannica Premium membership.\r\nAncient uses of the post-and-lintel were refined but not fundamentally altered until the production of cast-iron columns, which, offering greater strength and smaller circumference, greatly reduced the mass and weight of buildings. … Post and lintel construction is still used extensively in modern buildings.
The width of the lintel is limited not only by its tensile strength, but also by the length of …
The simplest illustration of load and support in construction is the post-and-lintel system, in which two upright members (posts, columns, piers) hold up a third member (lintel, beam, girder, rafter) laid horizontally across their top surfaces. Look at other dictionaries: POST-AND-LINTEL — The earliest, simplest method for spanning a space is the post and lintel system of upright posts to support a horizontal beam, called a lintel. Knossos: HALF-TIMBERING. Much modern construction in steel and concrete is based on the post-and-lintel system, restoring the formal simplicity of the oldest structures to modern architecture.
