摘　　要：针对工业基础类(IFC)标准中缺少对结构静力分析信息完善定义和描述的问题,文中对IFC标准中结构信息模型进行了研究,分别从分析环境、材料属性、几何构造、加载求解和分析结果5个方面将ANSYS结构静力分析信息需求和IFC标准中结构分析实体进行对比,总结出结构信息模型需要扩展的内容,并通过自定义实体类型方法在IFC标准中进行信息扩展,构建出一个面向ANSYS的结构静力分析模型,最后,给出具体实例验证其内容的真实性和有效性。本研究实现了在IFC标准中对结构静力分析信息的扩展、存储与表达,所创建的模型可在ANSYS中进行结构静力分析。Based on the problems of lacking a definition and description of structural static analysis information in the Industrial Foundation Classes(IFC) standard,the structural information model in the IFC standard was studied. The ANSYS structural static analysis information requirements and the structural analysis entities in the IFC standard were compared from analysis environment,material properties,geometric structure,loading solution and analysis result,and extension for structural information model was proposed. The information in the IFC standard was expanded by customizing entity type,and a structural static analysis model for ANSYS was constructed. Finally,a concrete example was given to verify the authenticity and effectiveness of the content. This study realized the extension,storage and expression of structural static analysis information in the IFC standard. The created model can be used for structural static analysis in ANSYS.
