［摘要］在超高层建设过程中，通过优化设计，解决了由建筑方案调整导致底部已经施工的柱轴压比超限的问题，避免了柱子加固设计，并节约了成本。一方面，通过概念设计调整了结构的传力路径，减小了传至柱子的轴力；另一方面，通过优化梁截面大小及布置减小了结构自重。最终使柱子不需要加固设计就能满足规范要求。

Abstract:In the process of super high-rise building construction, the optimization of design was adopted to solve the problem of out-of-code problem of the axial compression ratio of the bottom columns which were constructed before the adjustment of the architectural scheme, avoiding the reinforcement design of the columns and saving the cost. On the one hand, the force transmission path of the structure was adjusted through conceptual design to reduce the axial force transmitted to the column; on the other hand, the structure self-weight was reduced by optimizing the cross-sectional size and arrangement of beams. Ultimately the column cross-section could meet the regulatory requirements without reinforcement design.

Keywords:super high-rise building; conceptual design; optimization design; cross-section controlling of columns; control of axial compression ratio; reinfercement design
