Composite shear wall assembly could speed construction of steel frames

Score another small victory for more-constructible high-rises, especially in seismic zones. Results of recent load tests on a “sandwich” shear-wall assembly, designed to simplify and speed construction of core shear walls surrounded by steel frames, are equal to or better than anticipated, say researchers.

The sandwich, called a dual-plate composite shear wall because its steel-plate walls are filled with lightly reinforced concrete, is not for use only in seismic zones. “It is a great system for multihazard mitigation because it is good for seismic, wind and gravity loads as well as blast resistance,” says Ron Klemencic, president of Seattle-based structural firm Magnusson Klemencic Associates (MKA).
