590 Madison Avenue - Material and Structure

Material and Structure

The exterior of the building is covered by gray green glass and polished granite. The moderately reflective surface keeps changing its texture depending on the angle and the light. The use of transparent glass for the public space emphasizes its openness and lets plenty of sunlight in. The wedge shape building was a challenge in terms of structure because its shape caused more wind load than that to conventional box shape skyscrapers. After wind tunnel tests, original structural system was revised because of the wind load. The frames around the elevator shafts are kept as they were, then diagonal frames were added. Columns on the perimeter of the building were moved closer by half and the spandrel beams were strengthened. Surprisingly, after reconsideration of structure, the total amount of steel decreased. Another interesting the challenge in structure was cantilevered entrance. The point is not how to support the load above but how to keep the stability of the building. Using stronger and bigger columns for the base solved this problem.

Famous quotes containing the words material and/or structure:

    To one who habitually endeavors to contemplate the true state of things, the political state can hardly be said to have any existence whatever. It is unreal, incredible, and insignificant to him, and for him to endeavor to extract the truth from such lean material is like making sugar from linen rags, when sugar-cane may be had.
    Henry David Thoreau (1817–1862)

    ... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.
    Robert Musil (1880–1942)
