Performance-based seismic evaluation has emerged as a critical framework for understanding the realistic behavior of structural systems subjected to strong ground motions. The reviewed dissertation investigates the seismic performance of a steel moment-resisting frame (SMRF) through the integrated application of nonlinear static (pushover) and nonlinear dynamic (time-history) analysis using ETABS software. The study incorporates material and geometric nonlinearities along with realistic plastic hinge modeling to capture inelastic structural response. Key response parameters such as base shear, roof displacement, inter-story drift, and hinge states are systematically examined. The findings indicate that the structure achieves a maximum base shear capacity of approximately 43,166 kN in the X-direction and 2,452 kN in the Y-direction during pushover analysis, demonstrating adequate strength and ductility. Nonlinear dynamic analysis reveals comparatively higher displacement and drift demands due to cyclic effects and higher-mode participation. Overall, the structure satisfies Life Safety performance objectives under design-level earthquakes while maintaining sufficient reserve strength to prevent collapse. The study emphasizes the limitations of conventional linear analysis methods and highlights the necessity of adopting combined nonlinear analytical approaches for reliable seismic performance assessment of steel moment-resisting frames.
