基于工业基础类数据标准的结构模型转换技术

Transformation Technique of Structural Models Based on Industry Foundation Classes Standard

介绍了建筑信息模型数据共享与交换的工业基础类数据(IFC)标准,分析了IFC建筑模型与结构模型信息的组成与特点,研究了基于IFC的结构模型转换方法,采用ObjectARX技术在AutoCAD平台上开发了IFC结构模型文件生成软件.实例应用表明,该软件可以提取结构模型完整的IFC信息,可以实现从IFC结构模型到软件结构分析模型的转换.

Industry foundation classes （IFC） standard for data sharing and exchanging of building information modeling is introduced.The constitutions and the features of IFC files for architectural models and structural models are analyzed and compared.The transformation method of structural models based on IFC standard is investigated.The generation software of IFC files for structural models is developed with the ObjectARX technology on the AutoCAD graphics platform.A case study is implemented to illustrate the method of structural model transformation which shows that the software can extract the complete IFC information of structural models and it can realize structural model transformation from IFC standard to specific structure analysis software.
