（奧雅納工程顧問，上海 200031）[摘要] 深圳能源集團總部大廈項目由南、北塔樓及連接南北塔樓的連橋組成，北塔樓主體結構高208.5m（整體結構高寬比約為6.8，核心筒結構高寬比為17），南塔樓主體結構高l00m，南北塔樓在2~9層通過連橋連接，屬于復雜高層建筑。北塔樓結構體系采用了較為成熟且已在多項工程應用的框架體系+核心筒+加強層架的多重抗側體系。主要介紹了連橋與南北塔樓連接方式以及腰桁架、伸臂桁架設置位置的研究，并提出這些主要抗側力構件滿足中震彈性（不屈服）設計目標，特殊重要構件滿足大震性能目標。動力彈塑性時程分析進一步驗證結構在大震下的整體性能要優(yōu)于不倒塌要求。
[關鍵詞] 復雜結構；伸臂桁架；腰桁架；連體；連橋

( Ove Arup & Partners, Shanghai 200031, China)Abstract: Shenzhen Energy Group Headquarters Building is a complex high-rise buildings, which is a composition of 208.5 meters high North Tower, 100 meters high South Tower and a link bridge connecting two towers at 2^v 9floor. The H/W ratio of North Tower is 6.8, the H/W ratio of core is 17. Frame core-tube system with strengthened stories was adopted in structural system of North Tower. The analysis on the type of the link bridge connecting two towers and the setting locations of outriggers and belt trusses to enhance the system was introduced. Performance-based design was used in both structural system and single element throughout design progress. Main lateral members, such as the enhanced layers and link bridge area, were strengthened by improving seismic performance objectives or seisrmc measures. Nonlinear analysis( NLA) verifies that the structure of the overall performance of the building under heavy earthquake is better than code required (no collapse).
