This study delves into the realm of structural engineering, focusing on the optimization and
enhancement of Hybrid Diagrid-Base Isolation Systems (HDBIS) to bolster their performance in
earthquake-prone areas. Traditional construction methods for tall buildings in such regions pose significant
risks due to limitations in seismic resilience. The effectiveness of using Smart Base isolation systems in
diagrid and outrigger structures is examined. In response, HDBIS emerges as a promising solution, offering
robust earthquake protection, design flexibility, and cost-effectiveness. To represent effectiveness of base
isolation systems a fixed base model is compared with base isolated models of diagrid and outrigger
structures. Through meticulous examination and fine-tuning of HDBIS components, including diagonal
supports and base isolators, this research aims to tailor these systems for varying building heights and
seismic intensities. Leveraging advanced computer simulations and diverse control systems, the study
scrutinizes HDBIS behavior under seismic forces, focusing on movement dynamics, stress distribution, and
internal forces. Employing ETABS software, representative building models are meticulously crafted to
undergo comprehensive seismic response analysis, exploring critical parameters such as diagrid
configurations, isolator types focusing on Rubber based Isolation, displacement, drift, stress distribution,
and base shear. The findings of this research are poised to significantly advance the field of structural
engineering, providing valuable insights for the selection and enhancement of HDBIS, thereby elevating
seismic-resistant structural design practices.
