Abstract

The Steel Plate Shear Wall (SPSW) system is a seismic lateral force resisting system that has demonstrated good stiffness, ductility and energy dissipation capacity. However, SPSWs inherently block occupant movement, therefore they are often placed surrounding the building core. In order to accommodate openings, such as hallways and doorways, a pair of SPSWs are commonly placed adjacently. The Steel Plate Shear Wall with Coupling (SPSW-WC) configuration is composed of two SPSWs linked together by coupling beams at the floor level. The SPSW-WC configuration retains the benefits of the SPSW system while increasing material efficiency and introducing another form of energy dissipation. Although the SPSW-WC configuration is a promising form of the SPSW system, limited research has investigated this configuration. The goal of this work was to conduct a comprehensive study of the SPSW-WC configuration. The existing capacity design requirements for the standard SPSW system were extended for the SPSW-WC configuration. A large-scale experimental test program was conducted to further explore the performance of the SPSW-WC configuration. The level of coupling and the yielding behavior of the coupling beams, either flexure or combined flexure-shear, were the primary parameters of investigation. The behavior of the experimental test specimens is presented. The influence of the coupling mechanism is explored by comparing the response of the two specimens. Formalized design recommendations for the SPSW-WC configuration will enable easy adoption of this system.
