Reduce the story height and still frame in steel. Steel framing systems with a story
height as low as 8 ft. - 8 in. have been used successfully in a wide variety of
applications. Some of the successful systems and approaches include:
- Integration of conventional steel framing within the architectural program. This can
include architectural exposure of steel and/or concealing steel in architectural features,
such as walls and ceilings.
- The use of beam web penetrations in conventional steel framing, castelated steel
framing, stub-girder framing, truss-type framing or other "open" framing to
allow the mechanical systems to be located within the depth of the steel framing.
- The use of long-span steel deck or other floor assembly systems and construction that
places the floor slab either fully or partially within the depth of the steel framing.
- The use of a structural system such as staggered truss framing.
Many case studies of successful reduction in floor-to-floor height in steel framing are
listed in AISC's Modern Steel Construction
magazine.
