Abstract

The seismic resilience of multi-story buildings in earthquake-prone regions is a critical consideration in structural engineering. This dissertation presents a comprehensive analysis of the seismic performance of proposed multi-story buildings with varying heights (G+10, G+15, and G+20) using conventional, hexagrid, and octagrid structural systems. The study utilizes the Response Spectrum Method under seismic zone Ⅴ conditions to assess key parameters including storey drift, storey displacement, base shear, and overturning moment. Through nonlinear dynamic analysis, the seismic response of each structural system is evaluated, with a focus on categorizing bifurcations based on observed responses. The findings reveal significant variations in seismic performance among the different structural systems, with the hexagrid configuration demonstrating superior performance in mitigating seismic loads. The implications of these findings for seismic-resilient building design and construction practices are discussed, emphasizing the importance of adopting innovative structural systems to enhance seismic resilience and ensure the safety of built environments in earthquake-prone regions. This research contributes valuable insights to the field of structural engineering, informing stakeholders and decision-makers on effective strategies for mitigating seismic risks and creating safer built environments.
