［摘要］南京青奧中心會議中心地下2層，地上6層，由于其功能多樣性，建筑空間布置、流線設(shè)計十分復(fù)雜，經(jīng)比選最終采用鋼框架-中心支撐束筒結(jié)構(gòu)體系。著重介紹了該工程結(jié)構(gòu)體系的選擇過程、結(jié)構(gòu)體系的受力特點、基于性能的抗震計算原則及方法、整體計算結(jié)果、彈塑性時程分析結(jié)果。在大量分析計算的基礎(chǔ)上，提出了相應(yīng)的超限設(shè)計措施，使得結(jié)構(gòu)能夠更好地實現(xiàn)預(yù)定的性能目標。［關(guān)鍵詞］南京青奧中心; 超限復(fù)雜高層; 基于性能的抗震設(shè)計; 鋼框架-中心支撐束筒中圖分類號：TU391 文獻標識碼：A 文章編號：1002-848X(2016)11-0015-06
Structural design and analysis of the conference center of Nanjing Youth Olympic CenterZhang Xiongdi1, Zhang Fukui1, Yang Hong2, Ren Qingying1（1 China Architecture Design Group, Beijing 100044, China; 2 Shenzhen Huasen Architectural& Engineering Designing Co., Ltd., Shenzhen 510045, China）Abstract: The conference center of Nanjing Youth Olympic Center has 2 layers underground and 6 layers over ground. Because of its functional diversity and very complex architectural space layout as well as streamline design, the final structural system adopts the steel frame-center supported brace tube after the system selection. The selection process of the structural system of the project was introduced in detail as well as the mechanical characteristics of the structural system, performance-based seismic calculation principles and methods, the whole calculation results, and the elastic-plastic time-history analysis results. On the basis of a large number of analyses and calculations, the corresponding out-of-code design measures were put forward, which ensured the structure could better achieve the desired performance objectives.Keywords: Nanjing Youth Olympic Center; out-of-code complex high-rise building; performance-based seismic design; steel frame-center supported brace tube作者簡介：張雄迪，碩士，工程師，Email：zhangxd@cadg.cn。
