The study focuses on seismic behavior in multi-story buildings on sloped ground, highlighting the superior performance of the Step-back and Step-back Setback configuration. These insights contribute to optimizing building designs for enhanced seismic resilience in challenging terrains. The Step-back Setback configuration, with advantages in displacements, drifts, and shear values, emerges as a promising approach for structures in sloping areas. The findings inform future construction practices, emphasizing the importance of adherence to seismic design codes for structural integrity. While the study provides valuable insights, further research is recommended to explore additional variables and validate findings in diverse geological contexts. The study compares the seismic performance of Step-back and Step-back Setback building configurations with varying angles 15°, 20°, 25° and heights 24 m, 27 m, 30 m. Notably, the Step-back Setback design consistently demonstrates superior characteristics, such as lower displacements, reduced storey drifts 7–10% improvement, and more efficient resistance to lateral forces, particularly in comparison to Step-back configurations. The analysis adheres to IS 1893(Part 1):2016 standards, ensuring that observed values fall well within specified limits. The research concludes that Step-back Setback building frames exhibit enhanced seismic resilience, making them a preferable choice for construction on sloped terrains. Overall, the study emphasizes the importance of architectural and engineering features in minimizing structural vulnerabilities and promoting stability during seismic events. |
