为解决桥梁智能设计建造过程中建筑信息模型(building information modeling，BIM)向有限元模型传递信息的局限性，提出基于Revit建模软件二次开发的方法，提取并编译信息进行传递。利用Revit API以及C#语言对Revit软件进行二次开发，设计Revit外部命令插件接口进行模型信息传递。依托某预应力混凝土连续箱梁工程，验证模型信息传递方法的可行性以及程序接口传递信息的准确性。研究结果表明:通过对Revit软件的二次开发，可成功建立Revit模型与Midas模型的直接映射关系;设计的接口将Revit模型信息编译为Midas可读取的。mct命令流，可成功实现模型信息的传递，满足桥梁工程的设计需要。该方法解决了重复建模效率低下的问题，为探索研究"BIM+有限元分析"一体化提供参考。
Analysis of BIM model and finite element model bridge information transfer technology
In order to address the limitations of information transfer from a building information modeling(BIM)to a finite element model in the context of intelligent design and construction of bridges,a methodolo-gy based on the secondary development of Revit modeling software was proposed.This methodology entails the extraction and compilation of information for transfer.A secondary development of Revit software was cre-ated using the Revit API and C# language,with the objective of designing a Revit external command plug-in interface for the transfer of model information.The feasibility of the proposed model information transfer method and the accuracy of the program interface for transferring information were verified using a prestressed concrete continuous box girder project.The results of research demonstrate that through the secondary develop-ment of Revit software,a direct mapping relationship between the Revit model and the Midas model is suc-cessfully established.The designed interface compiles the Revit model information into Midas-readable.mct command flow,thereby successfully realizes the transfer of model information to meet the design needs of bridge projects.This method addresses the issue of inefficiency associated with repetitive modeling and pro-vides a reference for exploring and researching the integration of"BIM+finite element analysis.".
