Therefore, the purpose of this work is to present a comprehensive study of the SPSW-WC configuration as a seismic lateral force resisting system in high seismic regions. The conventional SPSW design procedure was extended for the SPSW-WC configuration. The design procedure was used to develop a suite of prototype structures. The fundamental response of the SPSW-WC configuration was explored through a mechanism analysis. Closed-form analytical expressions were derived based on the geometry and member sizes of a SPSW-WC frame for the ultimate strength and the degree of coupling, a parameter related to the proportion of the applied moment resisted by a vertical axial force couple in the piers. The prototype structures were analyzed using time history analysis under different levels of ground shaking. The performance of the SPSW-WC was compared with the conventional SPSW system. An experimental test program was developed to explore the response of the SPSW-WC with realistic fabrication techniques. Two half-scale specimens were constructed to represent the bottom three stories of two six-story prototype structures. The degree of coupling and the characteristic inelastic behavior in the coupling beams were the primary parameters that differentiated the two specimens. The specimens were subjected to a cyclic displacement protocol, with mixed-mode hybrid control algorithms used to emulate the demands on bottom three stories of a six-story structure. The experimental SPSW-WC specimens demonstrated robust cyclic performance that was consistent with the design intent. Both specimens reached 4% lateral drift, the maximum displacement that could be imposed by the facility, with minimal strength degradation. Additionally, a large amount of energy was dissipated during each test, with over 20% equivalent viscous damping observed in the 4% drift cycles.

Numerical simulations of the experimental specimens accurately captured the global and local behavior observed in the laboratory. The numerical modeling approach used in this study is shown to be an accurate tool for evaluating nonlinear response of the SPSW-WC system.
