摘要
数据标准是解决信息共享与交换问题的基础。IFC作为building SMART联盟发布的建筑信息模型数据交换的国际标准,用来实现建筑全生命周期中不同专业、不同阶段各软件之间的协同工作。目前在工程建设行业多专业的配合过程中,建筑与结构专业的信息交互最为迫切。在结构专业领域,构件偏心问题对结构模型的分析有着重要影响。基于建筑信息模型数据共享与交换的IFC标准,针对结构分析软件之间的模型数据转换问题,通过以SGF结构通用文件格式为基础的数据转换平台,提取偏心构件的数据表达并设计数据转换算法,运用C++编程语言,实现结构构件偏心数据的IFC表达。
Data standards are the basis for resolving information sharing and exchange issues.As the international data standard for the data exchange in building information modeling,industrial foundation classes(IFC),released by buildingSMART alliance,is designed to coordinate work of different disciplines and software at different stages throughout the lifecycle of buildings.At present,the information exchange between architectural and structural domains is the most urgent issue in the process of multi-specialty cooperation in AEC/FM(architecture,engineering,construction&facility management)industry.In the structural domain,the issue of eccentric members exerts a considerable influence on the analysis of structural models.With regards to the data conversion of different structural analysis software,this paper extracts the data representation of eccentric members,and designs a conversion algorithm for eccentric structural model through a data conversion platform based on the structural general format(SGF),which is used for data interoperability among various commercial structural software.Moreover,C++is employed in the research to achieve the transformation for the eccentric members of structure models using IFC format.
