摘　　要：为了解决大型工业建筑现浇混凝土结构设计效率低下等问题,提出三维分层参数化设计方法.该方法将现浇混凝土结构划分成相互关联的子结构,构建现浇混凝土结构的分层参数化模型;通过分析基于历史的参数特征造型技术的实现方法,提出分层参数化模型的变更传播机制和重构策略,实现对模型的快速设计与修改.文中方法已经在商品化的三维CAD系统InteRDS中得到应用,应用结果表明,其设计效率能够满足实际工程设计的要求.A 3D hierarchically parametric design approach is proposed to increase the efficiency of designing cast-in-place concrete structures of large complex industrial building.This approach constructs a hierarchically parametrical model consisting of interrelated sub-models,to represent the cast-in-place concrete structures which can be decomposed into various sub-structures according to material,function,or location.With a profound analysis of the history-based parametric feature modeling method,a new change propagation mechanism and rebuilding strategy is developed to support rapid design and modification.The proposed method has been implemented in a commercial 3D CAD system called InteRDS,and the application results show that the design efficiency of this approach can meet the needs well in practice.
