摘　　要：结构分析视图(MVD)定义了结构设计与分析工具之间信息交换的IFC数据模型,目前building SMART国际发布的是基于线、面宏观单元的结构分析视图定义,不能适应实体单元精细化结构分析模型的信息描述与传递。本文基于实体单元结构分析模型的交换需求,扩展了IFC结构分析模板中结构行为实体和结构项实体,增加了结构体元件、元件元素、结构体作用和结构体响应等实体,分析研究了面向实体单元需求的结构体元件之间的拓扑关系、结构元件网格划分信息等关键信息表达,在不改变现有结构分析MVD框架和应用的前提下扩展了满足实体单元需求的结构分析MVD,并通过扩展的结构分析MVD实现了结构平台软件和通用有限元分析软件之间基于IFC的精细化结构分析模型的信息交换。The structural analysis view defines the structural analysis model which can be exchanged between the structural design applications and structural analysis applications.Currently,the structural analysis view definition issued by the buildingSMART International is based on the line or surface element,which cannot adapt to the information description and transmission of the refined structural analysis model based on the solid element.Based on the exchange requirements of the solid element structure analysis model,the structural activity entities and structural item entities in the IFC structural analysis template are extended,the structural body member,member element,structural body.action,and structural body reaction entity are added,and the topological relations between structural elements for the requirements of solid elements and the representation of key elements such as meshing of structural elements are analyzed and studied.Without changing the existing structure analysis MVD framework and applications,the structural analysis MVD that satisfies the requirements of the entity unit is extended,and the information exchange between the structural platform software and the general finite element analysis software is realized based on the IFC-based fine structure analysis model.
