基于Revit的BIM技术结构设计中的数据交换问题分析

Analysis on the Application Problems of BIM Technology based on Revit in Structural Design

BIM技术在结构设计中应用的难点在于结构分析软件与BIM建模d软件之间的数据转换。本文主要从IFC标准、Revit API以及基于Excel的数据交换等方面进行了数据交换测试,并对测试结果进行了理论分析,测试结果为:IFC标准仅适合结构物理模型的数据交换,后续的结构分析设计或实体配筋难以进行;基于Revit API二次开发的接口在进行结构分析设计上的数据交换上是可行的,但是存在诸如接口不稳定等问题;基于Excel的转换依赖于软件是否支持Excel数据文件的导入导出,但转换过程稳定。实际运用上,应当针对结构体系和模型复杂程度的不同,采用不同的转换策略。

Data exchange between structural analysis software and structural modeling using BIM tools has been a key problem in terms of the application of BIM technology in structural design. This paper discusses the current state-of-the-art of the advantages and disadvantages on data exchange issues from the aspects of IFC standard, Revit API Platform and Excel data format, and then the theoretical analysis is conducted after the test. The test results show that IFC standard is only suitable for the information exchange of structural physical model, and the sequential structural analysis and reinforcement entity configuration receives very huge restriction; the information interface based on Revit API is feasible in structural exchange analysis and design, however, there are many problems such as the instability of the interface to be solved and the method based on excel file format is stable during the data ex- change process, however, it depends on whether the software can export and import excel file. Finally, different data exchange strategies should be adopted according to the type of the structural system and the complexity of the model.
