摘要
建筑信息模型(BIM)在土木建筑行业的应用得到了广泛关注,相关技术在工程实践中迅速发展与推广。智能化的BIM模型未来可能会逐渐替代传统图纸文件,建筑行业各方将更多采用BIM技术,朝着无纸化的方向发展。为了更好地保障结构在施工建设和运营管理期间的安全性,实现BIM模型向结构分析模型的自动转换,拓展模型的结构受力分析功能显得尤为重要。目前,某些有限元分析软件已开发相关模型转换接口,但若是针对复杂结构的精细化分析,则存在较多困难,往往还需要重新建模。本文基于C#语言编制BIM核心建模软件Revit与商用有限元软件ANSYS的程序接口,通过边界表达B-REP描述模型几何实体,实现BIM模型向有限元精细模型的自动转换,可为复杂结构精细化分析提供基础,具有良好的工程应用前景。
Engineering application of Building Information Modeling( BIM) technology is undergoing a rapid development and fast promotion in China,and wide applications in civil engineering attract more and more attentions. A tendency in the future is to promote BIM technology in civil structure design and construction,and BIM model will replace drawing documents. To ensure the structural safety in the whole period of construction and service operation,it is necessary to develop structural analysis function of model,and thus realization of automatic conversion from BIM model to finite element( FE) model becomes important. Although model conversion interfaces have been implemented in some FE software,it is still rather difficult for refined analysis of a complex structure,and normally is required to re-establish FE model which is very time-consuming and laborious. This paper proposed a programming interface between BIM software Revit and FE software ANSYS,which describes the model geometric entities by using the boundary representation B-REP,and is able to realize automatic conversion from BIM model to refined FE model. This technology could be a foundation for a refined structural analysis of complex civil structures, and thus it has a very promising prospect for engineering application.
