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。
In order to solve the optimization design problem of a towering structure, based on the parametric design and finite element method, the finite element method of wind and seismic loads is discussed, and the deformation and stress distribution of the tall structure under wind and earthquake loads are analyzed respectively , Combined with APDL language and Design Opt tool in ANSYS, a general-purpose finite element analysis software, to optimize the design and determine the cross-sectional dimensions of each beam and rod unit reasonably. The method avoids the complicated manual calculation and verification in the traditional design method, and improves the design precision and the efficiency.
