［摘要］人民日报社报刊综合业务楼是国内第一幢全面采用屈曲约束支撑为主要抗侧力构件的高层钢结构建筑。主体结构同时具有平面、竖向不规则，主要构件形态复杂等特性。详细介绍了该工程的结构设计难点和处理办法，其中包括屈曲约束支撑的布置、复合弧形桁架式竖向构件的布置特点及受力特征、环桁架的设置与分析等，同时介绍了如何运用性能化设计方法对不同结构部位和构件进行加强。

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
