某超高层建筑主体高度236.6m,属于超B级高层建筑,采用型钢混凝土框架-钢筋混凝土筒体结构。根据该工程特点和《高层建筑混凝土结构技术规程》(JGJ3-2010)有关结构抗震性能设计的最新要求,详述了结构抗震性能目标、针对超限的措施、结构优化过程、弹性反应谱分析以及弹性和弹塑性动力时程分析等内容。通过结构的计算分析表明,结构基本能够达到预期的抗震性能目标。
The height of a super high-rise building is 236.6 m and the structural system of steel reinforced concrete (SRC) frame-reinforced concrete (RC) core tube is applied. Based on its structural characteristics and the latest requirements about performance-based seismic design from Technical Specification for Concrete Structures of Tall Building (JGJ 3--2010), the performance objectives, seismic measures, structural optimi- zation, elastic response spectrum analysis, elastic and elasto-plastic dynamic analysis are discussed in this pa- per. According to the analytical results, the expected seismic performance objectives are basically reached.
