Dynamo在T梁桥建模中的应用

Application of Dynamo in T-beam Bridge Modeling

为解决T梁桥梁精准化建模难度大,异型结构复杂,建模速度慢等难题,采用“Dynamo+Revit”的参数化建模方法,开发了一整套建模编程,对模型定位、路线精准度进行校正,提出脱壳法定位湿接、横隔板的建模方法,并利用Dynamo的可视化编程优势实现这一理论,解决Revit中桥梁异型结构建模难点,最终实现一键式建模,既提高了桥梁设计师的工作效率,又保证了T梁桥异型结构的精准度,也为其他类型桥梁异型结构的构建提供了一定的借鉴作用,并通过山西省某装配式预应力混凝土连续T梁项目实例证明此方法在桥梁建模中的应用优势,降低装配式连续T梁建模难度,提高建模效率,为进一步实现BIM的正向设计提供技术支持。

In order to solve the difficulties of precise modeling of T-beam bridge,such as the difficulty of fine modeling,complex special-shaped structure and slow modeling speed,this paper adopts the parametric modeling method of“Dynamo+Revit”,develops a set of modeling programming,innovatively puts forward the modeling idea of positioning wet joint and diaphragm plate by shelling method,and realizes this theory using dynamo s visual programming advantages,and finally realizes one key modeling,which improves the performance of the system.The work efficiency of bridge designer not only ensures the accuracy of T-beam bridge special-shaped structure,but also provides a certain reference for the construction of other types of bridge special-shaped structure.The application of this method in bridge modeling is proved by an example of a prefabricated pre-stressed concrete continuous T-beam project in Shanxi Province,which can reduce the difficulty of assembly continuous T-beam modeling,improve the modeling efficiency and the efficiency of modeling,as well as providing technical support for one-step implementation of BIM forward design.
