Steel Bridge BIM Information Management For Structural Behavior

BIM technology is widely used in the current engineering field.It was first applied in the field of construction engineering.It was later slowly introduced into the municipal transportation industry.Bridge engineering is an integral part of municipal transportation.The research of BIM technology based on bridge engineering is very important.Due to the large number of specialshaped components of V-shaped rigid frame bridges,and including a large number of project information,how to efficiently design and construct them and effectively manage related structural information and performance information has become a bridge.The most important thing.This article is mainly based on the Guitian New Area Minmin Road across the Chetian River Bridge as a background project,through the establishment of Revit 3D geometric model and the use of Dynamo and other secondary development software to establish the project information model for information management and query.The first is to collect the current application of BIM technology in various countries and in various fields.Secondly,it shows in detail the establishment process of the 3D geometric model based on the Revit platform and the advantages of BIM visualization design.The accuracy of the BIM model achieves the construction accuracy of lod300.The relevant design stage and construction stage information are loaded into the three-dimensional geometric model,and its own information model is constructed.At present,there is still no uniform standard for the classification and coding of bridge BIM information at home and abroad.Each country has its own set of systems and rules.This paper mainly refers to the National Bridge Database(NBI)and open bridge information of the United States.The model(OpenBrIM)elaborates the characteristics of the top information and the bottom information of the bridge,and combines information classification and coding to summarize a set of middle-level information models suitable for the diagonal leg bridge to facilitate the management of bridge performance information.Through Dynamo and SDK development kits to improve the efficiency of information input and output,customize the information management module for their own projects.The most important thing in the information management of bridge engineering projects is the management and utilization of their performance information.Therefore,taking the antifatigue design of steel bridge panels as an example,it shows how to use the family manager and custom secondary times in Revit.Develop a system management of UI information on fatigue checking information,and how to use tools to efficiently process and utilize performance information,analyze the advantages and disadvantages of information management,and use the SDK development kit to develop UI interface features.Finally,an information model based on bridge performance information was constructed to study how to effectively use information model-aided design and verification during the design phase.At the same time,it can effectively integrate performance information into the entire life cycle of a bridge project to make information more effective.Ordered and non-destructive,in order to integrate the threedimensional geometric model and information model into one and serve the project.
