Experimental Research on Steel Plate Shear Walls for Seismic Design and Retrofit of Building Structures

A two-phase experimental research project was developed between MCEER and NCREE to investigate the performance of steel plate shear walls. Phase I includes quasi-static tests on half scale single-story single-bay penetrated steel plate shear walls. Phase II consists of dynamic tests as well as cyclic tests on a full scale two-story one-bay steel plate shear wall.

Phase I

To develop a better understanding of the behavior of steel plate shear walls that allow for the passage of utilities through the plane of the wall and formulate a method for efficient design of the anchor beams located at the top and bottom levels, quasi-static tests were carried out on half-scale single-story single-bay steel plate shear walls with penetration (one specimen with multiple holes and the other with quarter-circle cutouts at the corner of the boundary frame. These two variations on the solid fill panel system would exist in a retrofit situation.) by using low yield strength (LYS) steel infill panel and reduced beam sections (RBS) at the end of the beams.

Specimen (Phase II)

To investigate the behavior the intermediate beam of steel plate shear walls system subjected to seismic loading and the residual capacity of steel plate shear walls after severe earthquake, pseudo-dynamic test and subsequently cyclic test were carried out on a two-story one-bay steel plate shear wall with A36 steel infill panel and reduced beam sections at the end of the beams.

Michel Bruneau, MCEER Director and Professor, Department of Civil Structural and Environmental Engineering, University at Buffalo; and Keh-Chyuan Tsai, NCREE Director and Professor, National Taiwan University led the project. Graduate students Darren Vian and Bing Qu from MCEER and Ying-Cheng Lin, Chih-Han Lin from NCREE were also involved this project.
