Sažetak
Recent seismic events have highlighted the vulnerability of buildings in high-risk zones, resulting in substantial damage and economic loss. This study investigated the effectiveness of fluid viscous dampers in enhancing the seismic performance of a 10-story reinforced concrete building located in Jakarta, an area highly susceptible to earthquakes. A comparative analysis of the seismic responses of both conventional and damped buildings was conducted. A series of linear time-history analyses were performed employing seven spectrally matched ground motions, targeting the maximum considered earthquake level response spectrum. Key seismic performance parameters, including dynamic characteristics, base shear, roof acceleration, interstory drift ratio, and energy dissipation, were examined. These findings demonstrate that the incorporation of FVDs results in significant reductions in the fundamental period of a structure, base shear, and roof acceleration. Furthermore, a substantial reduction in the interstory drift ratios was observed, in conjunction with a significant increase in the overall energy-dissipation capacity of the building. These findings position FVDs as an effective and suitable solution for improving the structural resilience.
