This study presents an in-depth investigation of seismic performance between flat slab and reinforced concrete (RC) frame structural systems using nonlinear static pushover analysis. This nonlinear static analysis technique generates capacity curves that identify potential failure modes, assess displacement demands, and determine performance levels for each structural system. The goal is to offer better directional insight into the variations of the structural performance for stability, safety, economic efficiency and to flag the pros and cons of each system. This study is significant for addressing the cases of seismically active regions where structural integrity is a key factor and small perimeter change can create disaster. The investigation employs methodology to evaluate the seismic capacity and performance of both structural systems under earthquake loading conditions. This study also evaluates fixed base conditions and uses material properties based on BNBC and geometrical properties of typical mid-rise buildings as limiting conditions. It develops detailed three-dimensional finite element models to simulate the nonlinear behavior of both structures. Results show that flat slab structures are more flexible and vulnerable to earthquakes, while RC frame buildings offer greater strength and better resistance to seismic forces. These findings highlight the importance of structural system selection in improving earthquake resilience.
