This paper first describes the development of component strength deterioration models that are needed to be able to perform the collapse assessment of SPSWs. Collapse assessment was then conducted on SPSWs designed neglecting the contribution of their boundary moment resisting frames to resist story shear forces as well as on SPSWs designed considering the sharing of story shear forces between the boundary frames and infill plates. Based on these assessments, seismic performance factors (i.e., response modification coefficient (R-factor), system overstrength Ω 0 factor, and deflection amplification C d factor) for both types of SPSWs were identified and compared. Adjustments to improve collapse performance and factors that affect collapse potential were presented. Collapse fragility curves for archetypes with various structural configurations were investigated. Findings from these analyses demonstrate that the infill plates of SPSWs should be designed to resist the total specified story shears, and that SPSWs designed by sharing those story shears between the boundary frame and infill plates will undergo significantly larger and possibly unacceptable drifts.
