| As the country’s economic capacity continues to increase,the requirements for the construction of transportation systems are also constantly increasing,especially in bridge engineering.The birth and development of BIM technology has brought a huge revolutionary concept of innovation and thinking to the civil construction industry,prompting China’s construction industry to keep up with the pace of the times and promote the construction industry to enter the development period of BIM.Therefore,in order to apply the BIM technology in the design stage of the bridge engineering to complete the modeling of the whole bridge,this paper develops the application of the secondary development based on BIM in the design of bridge reinforcement.The main work is as follows.(1)Through the analysis of the current research and application status of BIM technology at home and abroad,it can be clearly seen that BIM technology has broad application prospects in the construction field,and can also be compared,BIM technology and application and exploration abroad,China’s BIM technology The research has been relatively lagging behind,especially in bridge engineering,the development speed is relatively slow.(2)Since there are many versions of BIM definitions in the world at present,the article lists the definitions of BIMs by countries and different organizations,and thus has a more comprehensive understanding of the BIM concept,and at the same time summarizes some of the characteristics of BIM,in practice.In engineering applications,the strengths of BIM technology are used to develop their strengths.At the same time,a brief introduction to BIM’s related series of software,you can choose the software you need to build the actual project according to your needs.Understand some of the standards currently relevant to BIM technology in the world,and make some knowledge reserves for the secondary development of BIM technology.(3)Summarize some of the characteristics of the bridge design process,and analyze the obstacles existing in the current development of BIM technology,and analyze it from different angles,so as to provide ideas for the improvement of current BIM technology,and also promote the future BIM technology to pave the way.(4)Introduced the basic knowledge of Revit software concept and BIM secondary development technology,and summarized the process of Revit secondary development.At the same time,it also briefly introduced a plug-in and some common graphics created by Revit.Edit method,this plugin to secondary development of BIM,especially some people with weak computer programming skills.(5)Based on a large-span suspension bridge as a background,the modeling of BIM components is completed by parametric modeling.In the drawing of steel bars,a set of methods for drawing steel bars is summarized and analyzed.According to actual needs and capabilities,different methods are adopted.The drawing is done to complete the modeling work of the steel bar,and finally all the components are assembled in an orderly manner to complete the full bridge model. |
