Abstract: The rise in irregular building construction, driven by esthetics and limited land availability, has led to increased vulnerability to lateral loads. Designers are adopting response control systems (RCSs) to ensure occupant safety and mitigate the risk of structural failure. Among the widely used RCSs are base isolators and dampers. This study examines the use of base isolators and viscoelastic dampers in 10‐story L‐shaped reinforced concrete buildings. The research evaluates buildings equipped with RCSs individually and in combination, analyzing parameters such as peak story displacement, inter‐story displacement ratio (ISDR), and peak story shear. The findings reveal that incorporating viscous energy dissipators (VEDs) at the edges of base‐isolated buildings significantly reduces structural responses. Specifically, reductions of up to 62.27% in peak story displacement, 52.03% in ISDR, and 64.72% in peak story shear are achieved compared to a fixed‐base structure. These results demonstrate that combining base isolators with strategically placed VEDs is highly effective in enhancing the performance of L‐shaped RC buildings under lateral loads. The study concludes that edge placement of VEDs in base‐isolated structures provides optimal response mitigation, offering a promising solution for improving the resilience of irregularly shaped buildings.
