摘要
当前,在各种商业软件盛行的环境下,设计单位最紧迫的问题是要解决本单位各专业之间的信息交互,而在这些信息交互中,建筑与结构专业的信息交互最为急需。针对这一需要,本文介绍了现今国际上建筑信息模型的数据共享与交换的IFC标准,分析了建筑模型与结构模型信息的组成与特点,研究了通用建筑结构有限元模型的表达方法,建立以IFC标准为基础,通过建筑模型自动生成符合多种结构分析与设计软件的结构模型的基本方法。通过实例验证本研究方法的实用性与可行性,结果表明本方法为各种设计软件间信息的共享与交换提供了一种通用解决方案,为企业内部实现建筑设计集成化提供了技术保障。最后,文章讨论了该研究方向中基于IFC标准的建筑模型的结构构件偏心、节点连接、荷载处理等方面的问题和后续研究方向。
One of the common problems in the building design industry is the direct information exchange and data sharing without relying on manual interpretations among various disciplines in building design. Of these information exchange and sharing, that between the architectural and structural professions is the most critical one. Realizing such a demand, this paper introduced the IFC standard for building information modeling, compared the representations and features of architectural and structural models, and studied the general representation technique of finite element model of buildings. An algorithm for structural model construction from the IFC-based architectural model was proposed together with an illustration example. The example shows that the proposed method represents a general solution for the information sharing and exchange between multiple CAAD and structural design software applications. The technical support for the implementation of an integrated building design approach is presented. A number of issues in the related area, such as representation of member offsets, clear identification of connected joints, loading extraction in the IFC-based architectural model, are discussed with some details for the extension of the present work.
