The purpose of this paper is to propose a new method of elastic seismic-deformation constrained design of frame-steel plate shear wall systems. In place of a global coordinate system, a member-coordinate system is utilized to measure the interstory-drift component without the rigid-motion component due to rotation of a floor. A set of bending stiffnesses of shear walls with columns is found such that the so-designed frame-shear wall system would exhibit a specified distribution of mean peak interstory drifts in the member-coordinate system to design-spectrum compatible earthquakes. Design examples for ten- and twenty-story models are presented for demonstrating the usefulness of this method of seismic-deformation constrained design. Finally time-history response analysis to an ensemble of design-spectrum compatible artificial earthquakes is performed to demonstrate the validity of this method and examine its accuracy.
