Problems solved by technology

[0004] However, most of the mainstream BIM software on the market is based on the development of the housing construction industry. At present, there is no BIM modeling software that adapts to the characteristics of bridge engineering. As a result, the current railway concrete-filled steel pipe tied arch bridge canno...

Abstract

The invention discloses an automatic building system and method for railway concrete-filled steel tube tied-arch bridge BIM, and belongs to the technical field of concrete-filled steel tube tied-arch bridge BIM model creation. Theautomatic building system comprises a Revit software module, a parameter design center, a Revit parameterization family library, an arch bridge parameterization family library, a Dynamo software module, an automatic parameterization modeling plug-in and an arch bridge BIM model. The Revit software module and the parameter design center are both connected with a Revit parameterization family library, and parameterization modeling is achieved in the Revit software module. Revit series software based on Autodesk is used for developing a parameterized component library, then Dynamo programming is used for writing an automatic modeling plug-in, secondary development is carried out, the parameterization degree of the model is greatly improved, parameterized and automatic rapid modeling is achieved, and management of the whole life cycle of a project is facilitated; the model is more standardized and easier to check, and the workload of structures of the same type is reduced.

Description

technical field [0001] The invention relates to the technical field of BIM model creation of concrete-filled steel tube arch bridges, in particular to a system and method for automatically creating a BIM model of a railway concrete-filled steel tube tied arch bridge. Background technique [0002] Since the 1990s, the number of CFST structures in my country has increased, and the bridge field is mainly used in arch ribs, lattice piers, bridge towers, truss beams and other structures [1]. There are various forms of arch bridge structure. Among them, in the field of long-span arch bridges, the arch ribs are mainly subjected to axial pressure. This kind of steel-concrete synergistic load-bearing concrete-filled steel tubular structure has shown great advantages. At present, there are more than 400 concrete-filled steel tube arch bridges in China. In recent years, the design and manufacturing technology of CFST arch bridges in my country have been improved, and the number of CFS...
