Heavily stiffened SPSW systems that were designed earlier were not very popular because of being uneconomical. During the Northridge (1994) and the Kobe (1995) earthquakes, SPSW systems behaved very satisfactorily which led engineers and researchers to study and employ unstiffened SPSW systems in a greater extent. However, seismic code provisions for these systems are still based on elastic force-based design methodologies. With ever increasing demands of efficient and reliable design procedures, a shift towards performance-based seismic design (PBSD) is necessary for these systems as well. The PBSD philosophy explicitly considers inelasticity in the lateral load resisting system along with preferring displacement-based design criteria to force-based criteria. In this paper, a new PBSD procedure for SPSW systems based on target inelastic drift and pre-selected yield mechanism is used. This design procedure is simple, yet it aims at an advanced design criterion. A 4-story test building is designed based on the proposed procedure for different target drifts under various earthquake scenarios. The designs are checked under the selected ground motion scenarios through nonlinear response-history analyses. The actual inelastic drift demands are found to be close to the selected target drifts. This shows the effectiveness of the new design procedure. In addition, the plastic hinge locations are also compared with the selected yield mechanism. Future modifications required for this design procedure for different SPSW configurations are identified based on these test cases.
