摘要:本文围绕AEC/FM领域应用软件的信息共享与互用，探讨了建筑建模软件与结构分析软件间的数据映射方案。基于IFC(Industry Foundation Classes)标准，分析了建筑物理模型与结构分析模型的异同，提出了从IFC建筑物理模型文件中提取结构构件以及结构构件连接节点拓扑信息的方法，并基于这些映射算法，利用C++编程语言实现了本文提出的通用结构分析模型(SGF)与IFC建筑物理模型的双向数据接口。最后，提出了以SGF为中心的多种建筑物理模型与多种结构分析模型的数据集成基本框架。
Abstract: Focused on information sharing and interoperability among software applications in the AEC/FM domain, this paper presents some solutions for data mapping between architectural modeling and structural analysis systems. Based on the Industry Foundation Classes (IFC) standard, the general architectural model and structural model are differentiated, and algorithms of obtaining the topological information of structural members and the connecting joints among structural members from architectural IFC physical file are deduced. Furthermore, based on these algorithms, the bidirectional data interfaces between the general structural analysis model (SGF) proposed by this study and the architectural IFC model are implemented by correlative C++ classes. Finally, based on the central SGF model, the whole framework for data integration of various architectural physical models and structural analysis models is proposed.
