| China’s construction industry market is broad,but for a long time there is a low production efficiency,information loss and other issues,resulting in a great waste of resources.The building information model(BIM)as a new production tool and production methods,since the proposed has been widely concerned,and now in Europe and the United States and other developed countries have been widely applied to the construction industry and brought revolutionary changes.The construction of the bridge model is obviously different from that of the building.In this paper,the arch bridge is taken as an example to explore the more convenient and efficient modeling methods.The following aspects are studied:(1)Based on the previous research,this paper summarizes the concept,characteristics and research status of BIM,introduces the modeling software related to BIM technology,and analyzes the application advantages and prospects of BIM in bridge engineering.(2)The concept of parametric modeling of arch bridge is put forward,and the concept of library in architectural modeling is introduced.According to the characteristics of bridge members,the bridge members are sorted and parameterized respectively.Parameterized library of components.(3)Through the study of Revit secondary development technology,the relevant processes and techniques of Revit secondary development are summarized.The secondary development technology can be used to expand the function area of the software,add the bridge tab page to Revit,and supplement the interface of the bridge page according to the bridge structure.Finally,the family of the library is called by the external command to realize the parameterization of the arch bridge Modeling.(4)Finally,the following practical works of the Creek Arch Bridge are used as the background,and the Revit software is used to model the secondary development.The process of modeling is introduced in detail,and the advantages and disadvantages of the application are summarized. |
