This study evaluates the effectiveness of viscoelastic damping systems (VDS) in improving the seismic performance of reinforced concrete (RC) beams. Using finite element analysis, RC beams with and without VDS were compared under different seismic loads. Results show that VDS greatly enhances seismic behavior, reducing maximum displacement by 49.8% and residual deformation by 62.4% under a 0.4g load. Energy dissipation increased by 52.4%, confirming the system's ability to absorb seismic energy. A parametric analysis identified an optimal VDS thickness of 20-30 mm. VDS performed consistently across various seismic intensities, proving to be a versatile and cost-effective solution for strengthening RC structures, especially in retrofit applications.
