南京青奥中心会议中心结构设计与分析

Structural design and analysis of the conference center of Nanjing Youth Olympic Center

南京青奥中心会议中心地下2层,地上6层,由于其功能多样性,建筑空间布置、流线设计十分复杂,经比选最终采用钢框架-中心支撑束筒结构体系。着重介绍了该工程结构体系的选择过程、结构体系的受力特点、基于性能的抗震计算原则及方法、整体计算结果、弹塑性时程分析结果。在大量分析计算的基础上,提出了相应的超限设计措施,使得结构能够更好地实现预定的性能目标。

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.
