Abstract：Thermal power plant is one of the most popular ways for electricity generation. Based on an actual thermal power plant building, a seismic resilient system was developed. Coal bunker isolation and supplemental metallic damping systems were adopted to address the detrimental effects due to the vertical and mass irregularities. A series of shaking table tests was conducted on a 1∶10 scaled test model to examine the seismic performance of the proposed resilient structural system. The responses under earthquakes in terms of peak drift ratios, amplifications in floor accelerations, damage in isolator and damping devices were discussed. The peak drift responses were below the limit required by the Chinese design code. The test results highlight the effectiveness of coal bunker isolation and supplemental damping devices in energy dissipation and protection of the structural components.
