| 摘 要： | 燃煤火力发电是目前主流发电形式之一。文章基于一实际火力发电厂主厂房结构，对其结构布置不规则与重型煤斗引起的质量不规则特点，采用煤斗隔震与附加金属消能器技术,发展了该火电厂主厂房的减隔震结构体系。为考察该火电厂主厂房减隔震结构体系的抗震性能，设计1∶10缩比试验模型并开展振动台试验。分析结构层间位移响应、楼层加速度放大系数、隔震层与消能器耗能损伤情况，试验结果表明：试验模型的层间位移角响应满足规范位移限值要求，煤斗设备隔震和附加消能器有效发挥耗能作用，保护结构构件不发生损坏。

| 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. |
