Post+and+Lintel

Post and Lintel

 This system consist in two upright members such as posts, columns, piers to hold up a third member like a lintel, beam, girder, rafter that is laid horizontally across their top surface. The job of the lintel is to bear the loads that rest on it without deforming or breaking. This will be give by the material, when the material is too weak or the lintel is too long it will break. Lintels composed of materials that are weak in bending, such as stone, must be short, while lintels in materials that are strong in bending, such as steel, may span far greater openings. 

From prehistoric times to the Roman Empire, the post – and – lintel system was the root o f architectural design. Th e interiors of Egyptian temples and the exteriors of Greek temples are delineated by columns covered by stone lintels



Disadvantages: The biggest disadvantages to this type of construction is the limited weight that can be held up, and the small distances required between the posts. Roman developments of the arch allowed for much larger structures to be constructed.
