The structural dynamics of buildings plays a critical role in their seismic performance and overall stability. Understanding the impact of mass distribution on natural frequencies and mode shapes is essential for optimizing the seismic design and retrofitting strategies of such structures. Finite element analysis is used in the research to model various mass distribution scenarios in a reinforced concrete frame and systematically analyses their effects on natural vibration characteristics. The results highlight how variations in mass distribution can lead to significant shifts in natural frequencies and mode shapes, emphasizing the importance of accounting for this factor in structural design and assessment. Furthermore, implications for seismic resistance and dynamic behaviour are discussed, providing valuable insights for engineers and designers aiming to enhance the performance and resilience of reinforced concrete building frames in earthquake-prone regions. © 2024 The Authors.
