Preliminary Research of Performance Levels and Objectives for Steel Structure with Energy Dissipated Dampers

DENG Xue-song,TANG Tong-bi,ZHOU Yun,GUO Yong-heng (School of Civil Engineering,Guangzhou University,Guangzhou 510006,China)  
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.
