摘　　要：阐述了框筒结构优化设计基本理论,探讨了运用ANSYS软件进行框筒结构优化设计的有关方法。以某18层框筒结构办公楼为例,先进行柱截面优化设计,再对优化后的设计模型在地震波作用下进行抗震变形验算与分析。研究结果表明,优化设计后不仅可使柱子成本降低28.168%,而且框筒结构的弹性层间位移角仍然满足抗震性能要求。This paper expounds the basic theory of optimizing designs for frame-tube structures and explores methods of achieving this goal with the application of ANSYS software. With an 18-storeyed office building in the frame-tube structure as the research subject, the procedures begin with an optimized design for the column cross-section, followed by the computation and analysis of the elasto-plastic capability of optimized design models under the action of seismic waves.The findings show that the optimized design models for the column cross-section could reduce the cost of concrete columns by 28.168%. What＇s more, the elastic inter-laminar displacement angle of the frame-tube structure still comes up to the anti-seismic standard all the same.
