摘　　要： 介绍了钢结构的破坏特点和耗能减震钢结构的特性。结合国内外相关研究成果及相关规范,将位移型耗能减震器的性态划分为无耗能状态、初始耗能状态、正常耗能状态、极限耗能状态和破坏状态,并对它们所对应的状态进行了描述,给出了量化的指标;在此基础上,从整个结构、结构构件、非结构构件及建筑附属系统、人员安全和使用情况四个方面对耗能减震钢结构的性能水准进行了综合性描述,给出了量化指标。最后,对耗能减震钢结构宜采用的性能目标提出建议。 Damage features of steel structure and characteristics of steel structure with displacement-dependent dampers were introduced.Based on the research results of other authors and relevant codes,performance of displacement-dependent dampers were divided into without energy-dissipation state,initial energy-dissipation state,normal energy-dissipation state,ultimate energy-dissipation state and failure state.The description and quantization index for the four states were put forward.Also,the synthetic description for the performance levels of steel structure with dampers and its quantization index were performed based on structure system,structure components,nonstructural components and auxiliary equipments,personnel safety and service condition.Finally,the suitable performance levels of steel structure with dampers were suggested.
