大跨度网壳复杂结构BIM建模关键问题对策研究

Research on key Problems in BIM Modeling of Large-Span Reticulated Shell Complex Structures

针对大跨度网壳复杂结构施工难度大、构造复杂、节点众多等特点,开展了BIM技术在其结构工程建模及展示的应用研究。首先,以某料棚为例,分析了BIM技术在大跨度网壳及复杂异形墙体结构建模及应用中的问题与难点,并对其关键性建模技术进行研究讨论。其次,利用BIM族功能及SSBIM有效的解决了模型创建过程中的关键问题。最终,建立了满足要求的BIM施工模型。

Aiming at the characteristics of large span reticulated shell complex structure,such as high construction difficulty,complex structure and numerous nodes,the application research of BIM technology in its structural engineering modeling and exhibition was carried out.Firstly,taking a material shed as an example,this paper analyzes the problems and difficulties of BIM technology in modeling and application of large-span reticulated shell and complex special-shaped wall structure,and studied and discussed its key modeling technology.Secondly,the key problems in the model creation process are effectively solved by using BIM family function and SSBIM.Finally,the BIM construction model that meets the requirements was established.
