摘要:结构耐久信息模型是用于建筑结构耐久性分析的信息模型，其包含设计, 施工, 维护等耐久性相关的信息。本文根据耐久性分析理论，提取耐久性影响因素，在已有的结构、施工信息模型的基础上通过扩充耐久信息建立了结构耐久信息模型，并从耐久信息模型方面扩展了现有的IFC标准，从而完善了IFC标准结构信息模型，也促进了结构耐久性评估软件系统的开发。

Abstract: Structural durability information model is the model which is used to analyze structure durability, including designing, construction and maintenance information. In this paper, the durability analyzing theories were comprehensively studied, and the relative effecting elements were abstracted. By extending existing structural model and construction model with durability information, the structural durability BIM was proposed, and the IFC information models were also extended with durability properties. The proposed results of this paper provided technical supports for developing durability analyzing software system based on BIM and improved the IFC standard.
