基于“Revit+Dynamo”模式的现浇连续梁桥设计建模

Design and Modeling of Cast-in-Place Continuous Beam Bridge Based on Revit+Dynamo Mode

现浇连续梁桥由于整体性好、适用性强、受力合理等优点,已成为被采用最广泛的桥型之一,同时,BIM技术在基础设施建设中的价值越来越举足轻重,但BIM技术在现浇连续梁桥的建模中仍存在很多困难。为解决现浇连续梁桥设计建模中,上部结构复杂、整体速度慢等困难,本文通过采集线路设计线数据、创建Revit参数化构件族、编制桥梁Excel构件参数表、编制Dynamo自动建模程序,提供了一套基于“Revit+Dynamo”模式的完整现浇连续梁桥设计建模方法,实现了空间异形的上部结构构件创建,以及下部结构的快速建模。大大提高了建模的精细化程度和效率[1],为现浇连续梁桥建设的数据提取、数据分析提供更可靠的依据。

Due to the advantages of good integrity,strong applicability and reasonable stress,the cast-in-place continuous beam bridge has become one of the most widely adopted bridge types.Meanwhile,BIM technologies play increasingly important role in the value of infrastructure construction,but there are still many difficulties during the modeling process of cast-in-place continuous beam bridge.To solve those problems during the process of cast-in-place continuous beam bridge design modeling,such as the slow speed and the complex of upper structure,this research collected the data from circuit design line,created the Revit parametric components,prepared a list of the bridge Excel component parameters and provided Dynamo automatic modeling program,which in overall has presented a set of complete solution based on the pattern of"Revit+Dynamo"cast-in-place continuous beam bridge design modeling method.It enables to model the complex upper part of the structural components,as well as enable the rapid modeling process of bottom structural components.It has greatly improved the degree of refinement and has improved the efficiencies of modeling,also it has provided a more reliable basis for data extraction and data analysis of cast-in-place continuous beam bridge construction.
