津湾广场9#楼建筑总高度299m,为框架-核心筒结构,属超限高层建筑。介绍了工程的特点和结构设计情况,针对结构高度超限和竖向抗侧力构件不连续,采用了基于性能的抗震设计;并对结构进行多模型、多软件及弹性和弹塑性分析以及局部的补充验算,在宏观上把握结构薄弱部位,有针对性地采取加强措施。计算结果表明,结构的工作状态和性能均能达到设计的预期性能目标和规范要求。 Jinwan Plaza, 9 # Building, the total height of 299m, for the framework - the core tube structure, is an overrun high-rise buildings. The characteristics of the project and the design of the structure are introduced. Based on the discontinuity of the structure height overrun and the vertical anti-side-force component, the performance-based seismic design is adopted. The multi-model, multi-software and elastic and elastic- Supplementary checking, grasp the weak parts of the structure on the macro-level, and take targeted measures to strengthen them. The calculation results show that both the working status and the performance of the structure can meet the expected performance objectives and specifications of the design.
