Thanks to a number of key innovations, steel is playing a greater role in residential high-rises, senior and student housing, and taller mixed-use developments, says architect Jayshree Shah, AIA, NCARB, LEED AP BD+C, with the American Institute of Steel Construction (AISC). Michael Johnson, AIA, Founder/Design Principal at Carrier Johnson + Culture, says new structural approaches using steel have reduced floor-to-floor heights, getting closer to concrete slab thicknesses of 8–8½ inches. This allows more hospitality and residential buildings to take advantage of steel construction.
