What is the post and translation?
Post and Lintel is a design technique that contains two upright members called posts, with a beam, called a translation that connects to them through the summit. The design using posts and translations is one of the oldest known techniques. Post and Lintel Construction are widely used in contemporary buildings, from family houses to high ascending structures. The ancient Greeks and the Romans built Post and Lintel temples, whose ruins many people still travel to see. Many structures that survived were made of stone, but Stone lacks tensile strength to continue for long distances. The Romans overcame this problem using arches that promote much more weight than a flat translation. Roman constructed with arched stone bridges and aqueducts still occur throughout Europe, about 2,000 years after they were built.
The weak part of the post and the design of translations, translation or cross-member, was the subject of various innovations over time. Arches, crossed arches and safes were earlyImprovements. Fields are further developments that have increased the load -bearing capacity of part of the translation. The pilot is basically a number of triangles, wood or steel, sandwiches between two straight rays. Fields are used extensively on both the design and construction and construction of the bridge, because they support much more weight than simple, straight translations and are faster and easier to build than arches.
The 20th century improvement is a glulam, an abbreviation for "glued laminated wood". The lamination process is designed to increase the capacity of the gluulam burden. They can be made as traditional straight translations or curved both for aesthetics and to increase their load capacity. Glulamy is sometimes used where they are visible, because Azn's more attractive than steel.
The compression strength limits the load -bearing capacity of the post pillar, as well as the tensile strength limits the bearing capacity of the translation load. Stone contributionsThey have a very good compression power and can support large matter. Compared to wood or steel, however, stone columns are difficult and expensive for transport and cumbersome in the construction process. As a result, even though Stone has a significantly more compression force than wood, it is rarely used as a member of a modern construction.
