Novel high-rise shear-wall core system, consisting of tied steel-plate modules that are field-filled with concrete, has been used on two buildings.

The nearly 1.4-million-sq-ft 200 Park high-rise in San José, Calif., though only 300 ft tall, has taken Seattle’s 850-ft-tall proof of concept for SpeedCore—a novel modular steel-plate shear-wall sandwich system—to new heights.

SpeedCore leads the way in the American Institute of Steel Construction's Need for Speed campaign, which also includes SpeedFloor, SpeedConnection and speedier simple bridges.

The New York City Dept. of Buildings has granted permission to use SpeedCore in New York City. The high-rise lateral-load resisting system of tied dual-plate wall modules field-filled with concrete has the potential to slash superstructure construction time compared to steel frames with reinforced concrete cores.

There is good news for boosters of a modular system of tied dual-plate walls field-filled with concrete—dubbed SpeedCore for its potential to slash superstructure construction time compared to steel frames with reinforced concrete cores.
