| 摘 要： | 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。

| Abstract: | The 9# building of Jinwan Square is a frame-corewall structure and it belongs to the tall building beyond code limits with 299m height.The characteristic and structural design of the engineering were introduced.Performance-based seismic design was adopted because of height beyond code limits and discontinuous lateral force resisting member.The structure was analyzed with multi-model and several softwares,elastic and elastic-plastic analysis were carried out,and some parts with complex stress was made a chec... |
