摘要: 工程信息交换标准IFC中缺乏对结构动力信息完善的定义和表达.文中通过剖析当前IFC标准的结构信息模型,对其结构分析领域进行评价,分别从几何信息、荷载信息、材料信息、分析结果信息4个方面对结构有限元分析软件SATWE的信息需求和IFC标准相应的实体作对比,提出IFC标准结构分析信息模型需要扩展的内容.在遵循IFC标准EXPRESS语言表达规范的情况下全面定义动力荷载(地震作用)信息,描述结构动力分析信息所包含的内容.在EXPRESS-G图中构造和设计结构动力分析信息的基本框架,对IFC标准所支持的结构有限元分析信息进行扩展,为完善IFC标准的结构信息模型提供参考.

Abstract:

The IFC ( Industry Foundation Classes) standard for engineering information exchange is insufficient for defining and expressing structural dynamic information. In order to solve this problem,first,the existing IFC-based structural information model is analyzed,and some missing details of the model that support the structural dynamic analysis are evaluated. Next,the information requirements of the structural finite element analysis software SATWE are analyzed in terms of geometry information,load information,material information and analysis result information. Then,the information requirements are compared with the entities corresponding to the IFC standard,with which some extension suggestions about IFC-based structural analysis model are proposed. Moreover,the dynamic load information such as the earthquake action is defined according to the IFC-formatted EXPRESS representation criterion,and the contents of the structural dynamic analysis information are described. Finally,the basic framework of the structural dynamic analysis information is constructed in EXPRESS-G graph,which extends the structural finite element analysis information and provides some references for the extension of IFC-based structural information model.

Key words: IFC standard, SATWE, structural information model, dynamic analysis information, IFC entity extension
