SELF-CENTERING STEEL PLATE SHEAR WALLS

A self-centering steel plate shear wall (SC-SPSW) consists of replaceable thin steel web panels as the primary lateral load resistance and energy dissipation elements, and post-tensioned (PT) beam-to-column rocking connections that provide system re-centering capabilities. The behavior of this new structural system has been analytically and experimentally investigated at the University at Buffalo and the University of Washington, in the USA, and at the National Center for Research in Earthquake Engineering, in Taiwan, as part of a collaborative research effort. The purpose of this paper is to provide a brief summary of some findings to date from this on-going research. References are provided to the publications available at the time of this writing. Reports to be published in 2013 (after completion of this project) will include recommended design procedure and design examples.
