Research On Construction Scheme Of Cable-stayed Bridge Based On BIM Technology

As the theory of structural analysis of cable-stayed bridges matures,more and more design options are available to engineers.How to use software simulation to choose the best construction plan for cable-stayed bridges,and to reasonably avoid unnecessary problems that may occur in the actual construction process,etc.all these can bring engineers and create new ways to solve problems.The BIM technology is constantly being developed and researched,and the door to the intelligentization of civil engineering has been opened.Engineers can use BIM to formulate the construction plan of the cable-stayed bridge.From this article onwards,the Lake Bridge was the object of investigation.Revit software was used to create a cable-stayed bridge model,combined with Midas and ABAQUS finite element mechanics simulation software,to achieve the comparison of the data results of the two different construction methods of precast and cast-in-place.Which construction method is better.1.Under the IFC guidelines,the appropriate Revit model building window was selected,and the pier column family,beam family,tower family,and stay cable family were established using family files,and assembled in a reasonable splicing manner.2.With the help of the plug-in interface of the Revit software,use Navisworks to filter out the model building information,and then perform collision inspection.At the same time,according to the spatial relationship and actual experience,adjust the unreasonable collision by detecting the reasonable collision report,and finally adjust the model required for modeling..3.Use Midas to calculate the axial force,bending moment,and displacement of the bridge to judge whether the bridge is reasonable or not.At the same time,use ABAQUS to model and analyze the bridge tower,divide different grids,and obtain the stress state of the bridge tower under the force state.Provide a reasonable theoretical basis for the selection of construction schemes.
