Research On Parametric Design Of Concrete Box Girder Bridge Based On BIM

The development of BIM technology has promoted the application research of parametric design methods in the fields of construction and bridge engineering.At present,the parametric design of bridge engineering is mostly applied to specific structures,which lacks flexibility and cannot be applied to changing structural forms.The author selects the 3DEXPERIENCE platform as a tool to study the parametric design methods of concrete box girder bridges with many regular structural forms,and to compile a parametric design program with batch modeling functions.This thesis introduces the characteristics of the BIM parametric design application platform and compares the platforms.The 3DEXPERIENCE platform is selected as the research tool of this thesis to analyze the principle and process of parametric design;According to the structural characteristics of concrete box girder bridges,the basic parametric design idea and procedures for parametric modeling of box girder bridges in 3DEXPERIENCE are proposed;According to the process proposed by the author,the parametric design method of the upper structure of the concrete box girder bridge is explored.And the author has compiled a3 DEXPERINECE parametric application program for concrete box girder models of different road centerlines,variable spans and variable cross-sections;Applying the program to actual projects,the thesis examines the feasibility of the programs and its application in quickly outputting design drawings,reinforcement,structural calculation and analysis.The thesis also summarizes the shortcomings in the current BIM parameterized design based on the research process.
