Abstract

The increasing seismic vulnerability of low-rise buildings and the demand for sustainable construction materials have motivated the development of alternative earthquake mitigation strategies. This study proposes a material-based damping approach by integrating high-damping bio-based materials into low-rise reinforced concrete (RC) frame systems to enhance intrinsic energy dissipation. Seismic performance was evaluated through numerical modeling using Response Spectrum Analysis and Nonlinear Time-History Analysis. The damping contribution was represented by equivalent viscous damping and nonlinear hysteretic behavior. Structural performance was assessed based on interstory drift ratio, roof displacement, and cumulative energy dissipation. Results showed that the proposed system significantly improved structural response, reducing interstory drift and roof displacement by approximately 27–35% compared to conventional RC frames. The system also exhibited faster vibration decay, improved hysteretic response, and more stable energy dissipation. The optimum equivalent damping ratio was found to range between 6% and 7%, confirming the potential of bio-based materials as effective and sustainable seismic damping components
