Seismic design philosophy has progressively shifted from prescriptive, force-based methods towardperformance-oriented frameworks that quantify expected damage, loss, and functional continuity undervarying earthquake intensities. This shift is particularly significant for reinforced concrete (RC)moment-resisting frame buildings that possess plan irregularities such as L-, T-, and H-shaped configurations, which are widely used in practice for architectural and functional reasons
