All rights reserved. This form of construction has been around since ancient times and is a precursor to arch construction, which is more common today. Visit the Art of the Western World page to learn more. They built a massive civilization and filled it with some of the most notable examples of monumental architecture, or extremely large buildings, in the world. Failure occurs only when the material is too weak or the lintel is too long. Steel, concrete, and laminated-wood arches of the 20th century changed the concept and the mechanics of arches. - Definition & Examples, Art, Music, and Architecture Around the World, Introduction to World Religions: Help and Review, NYSTCE Music (075): Practice and Study Guide, Introduction to Business: Homework Help Resource, Educational Psychology: Tutoring Solution, DSST Health & Human Development: Study Guide & Test Prep. In this lesson, we'll explore the post-and-lintel system of Egyptian architecture and learn how the Egyptians created massive structures. …support in construction is the post-and-lintel system, in which two upright members (posts, columns, piers) hold up a third member (lintel,... Get exclusive access to content from our 1768 First Edition with your subscription. The lintel must bear loads that rest on it as well as its own load without deforming or breaking. Continued from page 1 . Natural B. Ambient C. Tertiary D. Analogous Uses and Types of Lintel in Construction. Omissions? The job of the post is to support the lintel and its loads without crushing or buckling. This is the basis for the evolution of all openings. study They used it to make entire buildings out of stone, which was much more difficult. just create an account.

As a post and lintel temple, the Parthenon presents no engineering breakthrough in building construction. Masonry posts, including those of brick, may be highly efficient, because loads compress the joints and add to their cohesiveness. Masonry lintels are inefficient because they must depend on the cohesiveness of mortar, which is weaker than the blocks it bonds; so, in masonry construction, lintels of monolithic (single-slab) stone, wood, and stronger materials are employed. Let us know if you have suggestions to improve this article (requires login). These massive columns could support the weight of a 70-ton slab of stone. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Stonehenge, an example of early post-and-lintel construction. Moving stones of this size and weight took incredible effort and some advanced engineering innovations. 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. They are made of cement concrete and have the following types. Some of these architectural forms have stayed with us to this day. imaginable degree, area of Arches may rest on light supports, however, where they occur in a row, because the thrust of one arch counteracts the thrust of its neighbours, and the system will remain stable as long as the arches at either end of the row are buttressed by walls, piers, or earth.
