[摘要] 为解决某高耸结构的优化设计问题，基于参数化设计思想和有限元方法，在论述风荷载和地震荷载的有限元处理方法，以及分别分析风荷载和地震荷载作用下该高耸结构变形和应力分布的基础上，结合APDL语言和大型通用有限元分析软件ANSYS中的Design Opt工具进行优化设计，合理确定各梁、杆单元的横截面尺寸。该方法避免了传统设计方法中繁杂的手工计算与验证，提高了设计精度和效率。

Abstract: In order to solve the problem of optimal design about a high-rise structure, the deformation and stress distribution ofa high-rise structure under the effect of wind and seismic load, whose finite element techniques was discussed, was solved respectively based on parametric design and finite element method. Based on APDL language and Design Opt tools in large general-purpose finite element analysis software ANSYS, the optimization of the structure was executed, and then the cross sectional size of elements about beams and bars was obtained. The method avoids the complex manual calculation and verification in traditional methods and improves design accuracy and efficiency.
