摘要:近年来，BIM技术正在建筑工程中得到了越来越广泛的应用，也极大地提高了建筑行业的效率，然而，现阶段BIM技术与结构分析工作仍未得到有效的集成。本文针对这一问题，利用BIM模型中的梁柱构件和墙板构件，通过几何清理与划分网格分别得到了梁单元与壳单元，实现了BIM模型和结构分析模型在表达体系与信息格式维度上的双重转换。案例分析表明，该方法可有效地实现BIM模型到结构分析的模型的转换，转换生成的模型可以满足精度要求，对BIM技术在结构分析中的应用有借鉴意义。
Abstract: In recent years, BIM technology has been widely used in the building engineering, which improves the efficiency of the construction industry greatly.However, structural analysis has not been integrated to the BIM technology effectively till now.In order to achieve the conversion between BIM model and structural analysis model both on the expression system and the data format, this paper gives anintegrating method including geometry cleanup and meshing, by which we can get beam elements and shell elements from BIM model.Case study showed that this method can be used to get precise finite element model for structural analysis from BIM model, which has a great value in terms of future application.
