基于BIM模型的结构设计审查方法研究

Code compliance checking of structural design based on BIM model

建筑信息模型(BIM)作为建筑工程的数字化表达,正在成为实现建筑全生命期信息化、工业化和智能化的重要手段。以BIM模型作为设计交付成果是未来建筑设计领域发展趋势。然而,现阶段建筑结构设计的审查工作还是以人工手动审查为主,普遍存在主观、效率偏低且易出差错等问题。因此,以框架结构模型审查为实例,通过关系数据库方法解析BIM模型数据,采用Java编程转译结构设计规范条文,提出一种基于BIM模型的结构设计审查方法。实现过程包括:①模型准备与信息映射;②规范条款分类和转译;③建立连接和代码执行。结果表明:该方法可以部分实现结构模型的自动化审查,提高了设计审查工作的科学性、可靠性和规范性,为今后全面实现设计审查的自动化和智能化提供了技术基础和参考方法。

Building information modeling(BIM),as the digital expression of construction engineering,is becoming an important means to realize the informatization,industrialization,and intelligence of the whole life of building.The utilization of BIM model as a design delivery represents the future trend of construction design.However,currently,the compliance checking of structural design is conducted manually,which tends to be subjective,inefficient and error-prone.As a result,this paper carried out a case study of the compliance checking of the frame structure,analyzed the BIM model data using the relational database,and employed Java programming to translate the provisions of structure design code,thereby proposing an approach to compliance checking of structural design based on the BIM model.The process can be divided into three main steps:①Model preparation and information mapping;②Provision classification and translation;③Development of connection and code execution.The results show that the proposed method can partially realize the automatic compliance checking of structural design,improve the scientificity,reliability,and standardization of conformance checking,and provide a technical basis and alternative method for the automation and intelligence of code compliance checking in the future.
