Post+and+Lintel

Post and Lintel

Stone, Brick, Wood, Cast Iron, Concrete, Steel

Lintels should be strong in bending

Post should be especially strong in compression

Lintel construction is the limited weight that can be held up

The combination of materials makes a better development of the post and lintel system

Two upright members (post, columns, piers) Third member (lintel, beam, girder, rafter) The basis for the evolution of all openings To support the weight of the structure located above the openings

Function to bear the loads that rest on it (and its own load) without Deforming or breaking to support the masonry above a window or door opening. Failure material too weak or lintel too long In non-classical architecture for ornamental purposes, no structural function

Made of wood, stone, steel or reinforced or pre-tensioned concrete Stone lintels must be short, weak in bending Materials strong in bending, bigger span, greater openings Masonry lintels are inefficient cohesiveness of mortar

Advantages The job of the post is to support the lintel and its loads without crushing or buckling. Masonry post, including those of brick, may be highly efficient, since the loads compress the joints and add to their cohesiveness.

Disadvantages The biggest disadvantage to a post and lintel construction is the limited weight that can be held up, and the small distances required between the posts. The tension induced by deformation of self-weight and the load above between the posts.
