Abstract
This project focuses on the seismic performance evaluation of RC structures of different heightsG+4, G+9, and G+14under Zone-V conditions using performance-based seismic assessment (PBSA) procedures. Nonlinear time-history analysis is employed to assess key parameters such as story displacement, drift, shear, and base shear. Results show that as building height increases, both story displacements and drifts intensify, with the G+14 building showing the highest values, indicating greater lateral movement. Maximum story shears rise with building height, emphasizing the need for advanced seismic design in taller structures. The G+14 building experiences the highest base shear in the X direction, while the Y direction shows lower forces. Performance assessments using El Centro earthquake data confirm that the Demand Capacity Ratio (DCR) for critical columns meets acceptable limits. Hinge responses remain within permissible ranges, ensuring seismic resilience. This analysis highlights the importance of tailored seismic design strategies for buildings of varying heights to ensure safety and stability under severe earthquake conditions.
