基于Dynamo模式+Revit二次开发的变截面连续梁桥初步设计研究

Preliminary design study of continuous beam bridge with variable section based on secondary development of Dynamo mode+Revit

针对变截梁桥建模困难、效率低下、精确度不足等问题,以鄂州市东沟大桥为工程背景,基于Revit+Dynamo模式提出一套搭建变截面梁桥参数化模型方案,成功搭建全桥三维模型,验证了该参数化模型方案具有可行性。并在此模型基础上,通过Revit API程序接口进行二次开发创建0#节段箱梁钢筋参数化模型,实现了桥梁工程参数化、自动化建模效果,期望能为同类型和其他类型桥梁参数化设计提供一些思路和参考。

In view of the problems such as modeling difficulties,low efficiency and insufficient accuracy of the bridge bridge,taking the Donggou Bridge in Ezhou City as the engineering background,based on the Revit+Dynamo mode,a set of parametric model scheme of the variable section beam bridge is proposed,and the three-dimensional model of the whole bridge is successfully built,which verifies the feasibility of the parametric model scheme.On the basis of this model,the reinforcement parametric model of 0#section box girder is created through the secondary development of Revit API program interface,which realizes the parametric and automatic modeling effect of bridge engineering,and hopes to provide some ideas and references for the parametric design of the same type and other types of bridges.
