How these connect

The steel skeleton frame and what it relates to. Every line is an evidence-backed relation, and the arrangement is fixed — this address draws this picture, today and next year.

  1. The curtain wall · depends_on · The steel skeleton frame

    An envelope can carry only itself and the wind on its face once the frame has taken over the building load; without the frame the wall must be structural.

  2. The steel skeleton frame · depends_on · Structural steel

    A skeleton frame needs a material strong in tension and ductile in failure, in repeatable rolled sections and at commodity prices - which is what the converter and open-hearth processes supplied.

  3. Home Insurance Building, Chicago · instance_of · The steel skeleton frame

    Its floors and external walls were carried on a metal skeleton, though the frame mixed cast iron, wrought iron and Bessemer steel and the masonry piers were not wholly relieved of load.

  4. Load path · governs · The steel skeleton frame

    The frame is defined by taking the load path out of the wall entirely and running it down a cage of columns, which is what releases the wall for other uses.
