Seismic Behavior and Design of Composite Steel Plate Shear Walls

This report presents information on cyclic behavior and seismic design of composite shear walls made of steel plate and reinforced concrete encasement walls connected to each other to act as a composite element. The cast-in-place composite shear walls have been used in a few structures in the United States and Japan. A hospital structure, where the composite shear walls are used is discussed and presented. Recently, the traditional and an innovative version of composite shear wall were studied and tested at the University of California at Berkeley by the author. The test results are summarized in this report. Using the available information, design guidelines for seismic design of composite shear walls made of steel plates connected to reinforced concrete walls were developed and are presented in this report. Finally, two configurations of composite shear walls that are believed to be efficient, economical and easy to fabricate are suggested at the end of the report.
