摘要 为解决桥梁结构分析过程中手动建模效率低且重复性强等问题,依托Revit和Midas/Civil软件平台,在Visual Studio开发环境下采用Revit API和C#语言,提出了一种BIM模型向结构有限元模型的自动转换方法,并设计了一种Revit向Midas/Civil的模型转换程序.以某连续梁桥工程为对象,通过访问BIM模型中结构构件对象存储的属性信息,获取桥梁结构分析所需的有限元建模参数,并转换成适用于Midas/Civil的语言格式,实现了有限元建模过程中结构参数信息的准确添加.在此基础上,根据桥梁有限元模型的应力分析结果,验证模型转换方法的可行性.结果表明,所提出的Revit-Midas/Civil模型转换方法可实现BIM模型向结构分析模型的自动转换,有效提高了桥梁结构分析的建模效率,弥补了BIM技术在桥梁结构分析方面的不足. To solve the problems of low efficiency and high repeatability of manual modeling in the process of bridge structure analysis,a method for automatic transforming from BIM(building information modeling)to the structural analysis model was proposed based on the platforms of Revit and Midas/Civil by using Revit API(application programming interface)and C#language under the development environment of Visual Studio software.Then,a program for model conversion from Revit to Midas/Civil was designed.Taking a continuous beam bridge as an example,the information of the finite element modeling parameters for bridge structure analysis was obtained by accessing the properties stored in BIM models of structural component objects,and then was converted into the language format applicable to Midas/Civil.The structural analysis parameter information in the process of finite element modeling was accurately added.The feasibility of the model conversion method was verified by the stress analysis results of the finite element model of the bridge.The results show that the model conversion method from Revit to Midas/Civil can realize the automatic transformation from BIM to structural analysis model.The method effectively improves the efficiency modeling of bridge structure analysis and makes up for the deficiency of BIM on bridge structure analysis.
