With the decentering complete of the fixed trusses that shape the daring kinetic roof of the Atlanta Falcons stadium, the steel erector is adding the eight movable parts, called "petals," that will close and open like an oculus.
As those on the leading edge know, progress in the buildings sector does not come easily. But that doesn't stop innovators from working diligently to increase the sustainability and resilience of buildings and decrease their carbon footprints while trying to find ways to boost construction quality and building-team productivity.
A recent series of dynamic tests demonstrates that there are several types and doses of steel-fiber reinforcement that can be used in performance-based seismic design of coupling beams—headers that link openings in concrete shear walls—to reduce rebar congestion.
Though the results are preliminary, the International Code Council has approved the updated structural building-design standard for inclusion as a reference standard in the 2018 edition of ICC's International Building Code.
