Hammerbeam Roof - Design

Design

A hammerbeam roof allows a span greater than the length of any individual piece of timber. In place of a normal tie beam spanning the entire width of the roof, short beams, the 'hammer-beams', are supported by curved braces from the wall, and further structure is built on top of the hammerbeams. A hammerbeam structure can also be regarded as a simple form of truss. Hammerbeam roofs can exert considerable thrust on the walls that support them.

Famous quotes containing the word design:

    We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.
    Joseph Addison (1672–1719)

    You can make as good a design out of an American turkey as a Japanese out of his native stork.
    —For the State of Illinois, U.S. public relief program (1935-1943)

    Westerners inherit
    A design for living
    Deeper into matter—
    Not without due patter
    Of a great misgiving.
    Robert Frost (1874–1963)
