It has strong lateral load resistance, high energy dissipation and good recentering capability. Numerical model with continuum elements is proposed since it is of importance for capturing the detailed behavior of SC-SPSW and investigating the effects of various parameters on web plate and PT connection behaviors. The calculated responses of models including hysteresis response, PT force, PT connection axial force and moment, web plate shear resistance are compared with the experimental data to validate the modeling method. The results present a good agreement in the system performance and the numerical model is able to account for more complex web plate behavior, including the web plate stress and strain development. Furthermore, this study proves that the thicker web plate increases the PT connection and boundary frame demands and has a negative impact on the PT force. The compressive stress in web plate increases with the increasing web plate thickness. And the compressive stress has an increasing trend after the web plate full yielding under the cyclic load. The research provides an effective modeling method for the parametric study on the SC-SPSW performance.
