Abstract: The People's Daily office building is the first comprehensive application of buckling resistance braces(BRBs) for major resistance to lateral force components of high-rise steel structure building. The building is a high-rise steel structure with characteristics of plane irregularity, vertical irregularity and complicated member shapes. The structural analysis and design were presented, and the key technique was introduced including BRBs layout, arcshaped vertical trusses layout and its loading characteristic, the ring trusses and its effect etc. The performance-based design method was used to guarantee the safety of the structure.

Keywords: high-rise building; steel frame; buckling resistance brace; seismic design; performance-based design
