This specimen was designed such that no boundary frame yielding occurred under earthquake excitations with a 2% probability of exceedance in 50 years, resulting in large and overly conservative column sizes. Simplified analytical procedures of using the tension-only strips to represent the web plate, and beam-column elements for the boundary frame capture the SC-SPSW overall responses well when the boundary frame remains elastic, as designed, under the cyclic loadings. However, this approach is not able to gain the insights into the local behavior of the PT beam-to-column connection such as local flange buckling and stress concentrations at the rocking connections. Thus, a detailed ABAQUS shell element model is constructed to analyze these local PT connection behaviors. The optimal boundary frame size is determined using the shell models by reducing the boundary element sizes while simultaneously ensuring that the desired level of performance is achieved. Based on these analyses, this paper summarizes the impact of varied boundary frame member sizes on the SC-SPSW performance.
