【摘要】 建筑结构建造和运营过程中关键受力构件的详细信息可以协助工程师对遭受灾害的结构进行灾害评估分析和防灾减灾。BIM技术是以工程为对象的包含其生命周期全信息的三维数字模型,在分析建筑结构可能遭受的灾害和其主要受力构件的基础上,系统研究了BIM模型中结构关键构件的几何、非几何数据信息的表达格式和定义规则。结合分析BIM面向工程生命周期过程中信息模型的集成模式和积累方法,设计了一种基于BIM全信息模型的结构灾害评估关键构件信息库框架。该框架提供了从BIM模型中提取和集成关键构件数据信息的整个流程和方法,结合基于internet网络平台或智能数字楼宇管理系统,可以为结构灾害评估中获取关键构件数据信息的应用平台开发提供研究基础。更多还原

【Abstract】 During the construction and service process of the building structures,the detail information database of the structural key elements is available for the hazard assessment,and the hazard prevention and reduction for civil engineers when the structures suffer hazards.Building Information Modeling(BIM) technology,which takes the project as an object,is a three-dimensional digital model containing all the information across the life cycle of the project.Based on the analysis of the possible structural hazards and the structural key elements,the paper studies the expression formats and definition rules of the geometrical information and non-geometrical information of the structural key elements in BIM model.Combined with the analysis of the information integration modes and accumulation methods of the BIM model across the life cycle of the project,an information database framework of key elements for the structural hazard assessment,which is based on the BIM model,is designed in the paper.The framework provides a whole flow path and method for extracting and integrating the information of structural key elements from BIM model.Based on the internet network platform or intelligent digital building management system,the framework can provide a research foundation for developing software application platform which can be used for extracting the important information of the structural key elements for hazard assessment.更多还原
