Parameterized Design Of PC Continuous Beams Based On BIM

With the increasing emphasis on BIM technology in the country,BIM technology has become more and more widely used in various industries of civil engineering,and engineers and technicians have carried out a lot of exploration and practice in the application of BIM technology in the design,construction,and management of engineering.This paper makes use of BIM technology to study the parametric design of PC continuous beams,and provides a reference for the application of BIM technology in bridge engineering.(1)Current status of research on parametric design of bridges at home and abroadBased on the study of the development status of BIM and the application status of BIM in parametric design,the necessity,research content and technical route of BIM technology in parametric design of bridge are put forward.(2)Parameterized Design Research Technology PlatformBased on the introduction of the characteristics of the BIM technology R&D platform,the selection,technical characteristics and realization of the parameterized design platform for PC continuous beams are put forward,which lays a foundation for the research on the parameter transformation of PC continuous beams.(3)Research on Parameterization Design Method of PC Continuous Beam Based on BIMBased on the analysis of the existing parameterized design ideas,methods and processes based on BIM,combined with the structural characteristics of PC continuous beams,the representative T-beams and box beams are studied.On the basis of the existing "slicing" parametric design ideas,the "grid" division method of vertical and horizontal segmentation is proposed,and the parameterization goal of PC continuous beam is well solved.At the same time,in order to facilitate the information management of the parameterized BIM model,the coding rules based on the "Highway Bridge Naming Number and Coding Rules" GB1108-89 are proposed.(4)Research on PC Continuous Beam Components and Overall Parameterization Design Based on BIMAccording to the established parametric design method,first,using the family model file of the Revit software as a template,the beam member is parameterized and designed using the release fusion method.Secondly,the parameterized design of prestressed steel bars of beams is realized by means of Dynamo plug-in.Finally,based on the Revit API interface,the PC continuous beam of the PC continuous beam family after the parameter is parameterized through the Visual Studio 2012 programming.(5)Parameterized design of PC continuous beam based on BIM is applied in bridge maintenance managementRelying on the background of a maintenance bridge in Beijing,on the basis of setting up the parameterized model of PC continuous beam BIM,the bridge information parameter management function is fully utilized,and the simulation and description method of the bridge disease information are shown.Through the study of PC continuous beam components and overall parametric design methods,the realization methods and approaches are explored,which can provide reference for future research in related fields.
