摘　　要：采用大型通用有限元软件ABAQUS对设置粘滞阻尼器的某常规岛主厂房结构进行了罕遇地震作用下的抗震性能分析,并与原结构进行了对比。对比分析结果表明:在大震作用下,设置新型粘滞阻尼器以后,结构的层间位移角均满足规范的要求,其抗震性能得到了显著提高,在震后可继续使用,研究为粘滞阻尼器在常规岛主厂房结构中的应用提供了坚实的理论基础。The nonlinear finite element analysis software ABAQUS is adopted to analyze the seismic performance and compared with the original structure. The analysis results show that under strong earthquakes, the structural interlayer displacement angle can satisfy the requirements of specification, its seismic performance is significantly improved and can continue to use after the quake after setting viscous dampers. Finally, the research provides a strong theoretical basis for the application of the new type of viscous dampers in the main machine hall in conventional is- land.
