    A jack arch is a structural element in masonry construction that provides support at openings in the masonry. Alternate names are lintel arch, [1] flat arch and straight arch.

    However, lintels are subject to bending stress, while the flat arches are true arches, composed of irregular voussoir shapes (the keystone is the only one of the symmetric wedge shape), [86] and that efficiently uses the compressive strength of the masonry in the same manner as a curved arch and thus requires a mass of masonry on both sides to ...

    en.wikipedia.org/wiki/Windpost

    As an alternative to steel windposts, when the primary structure is composed of reinforced concrete, secondary structures are cast in situ to provide lateral support to masonry panels. Traditional design methods are often not optimised for the design of masonry panels with openings, and therefore windposts can be over specified on walls where ...

    en.wikipedia.org/wiki/Voussoir

    The keystone is the centre stone or masonry unit at the apex of an arch. The springer is the lowest voussoir on each side, located where the curve of the arch springs from the vertical support or abutment of the wall or pier. [1] The keystone is often decorated or enlarged.
