［摘要］合肥某办公楼为结构高度205-250m的超限高层建筑，采用附带加强环带桁架的框架-核心筒结构体系。结构存在高度超限、扭转不规则、楼板大开洞、斜柱内收、竖向构件间断等不规则情况。利用SATWE及MIDAS对结构进行整体计算和弹性时程分析，采用MIDAS对结构进行动力弹塑性时程分析，采用ABAQUS对跃层柱进行屈曲分析。分析结果表明，结构各项指标均满足规范相关要求。最后通过概念设计对关键和重要构件适当加强，使结构满足各项抗震性能目标。

Abstract:An office building located at Hefei is a super high-raise building with  height of 205-250 meters. The frame-core wall structure with reinforced ring truss is adopted for the structure. The structure has irregularities such as height exceeding limit, torsion irregularity, large opening in the floor, slanted column adduction, vertical component interruption, etc.Programs of SATWE and MIDAS were used to perform the integral calculation and elastic time history analysis on the structure. The program of MIDAS was used to perform dynamic elasto-plastic time history analysis, and the buckling analysis of skip-floor column was performed by  using the program ABAQUS. The analysis results show that all the indices of the structure can meet the relevant specification requirements. Finally，key and important construction members were strengthened via concept design to ensure that they meet the goal of preset seismic performance objectives.

Keywords:super high-rise building; frame-core wall structure; ring truss; dynamic elasto-plastic analysis; performance-based seismic design
