Abstract:
The use of high strength reinforcement in seismic zones 3 and 4 dates back to 1979, in the design and construction of the Continental Plaza Building, Seattle, Washington, a 37-story concrete building. The design team comprised of Whitley-Jacobson Company, engineer of record; Neil Hawkins, Professor of Engineering, University of Washington; the fabricator, supplier of WWR, and the architect. A combination of shear wall and moment frame design was selected as the most economical lateral force resisting syst4em. Grade 75 WWr was used as horizontal reinforcement to confine the column cores.
