【摘要】：通过分析当前建筑工程项目模型信息传递中存在的典型问题及应用需求,提出IFC-API建筑结构模型转换模式,并结合前期结构分析模型转换框架,形成一套完整的基于BIM的面向结构有限元分析的模型转换体系,对解决设计阶段信息断层、提高效率具有重要意义;同时针对模型显示进行优化,扩展研发基于BIM的模型转换平台,并通过某一小学教学楼进行实例验证。该研究从理论、技术、应用层面就面向结构有限元分析的模型转换取得突破性进展,也为后续基于BIM的时变结构安全性能模拟和分析提供支持。
[Abstract]:Based on the analysis of the typical problems and application requirements in the information transfer of the current construction project model, the transformation model of IFC-API building structure model is put forward, and the transformation framework of the model is combined with the previous structural analysis model. Forming a complete model transformation system based on BIM for structural finite element analysis is of great significance to solve the information fault in the design phase and improve the efficiency, at the same time, the model display is optimized. The model conversion platform based on BIM is extended and verified by a primary school building. The research has made a breakthrough in the model transformation of structural finite element analysis from the theory, technology and application level, and also provides support for the simulation and analysis of the safety performance of time-varying structures based on BIM.
