Research And Application Of Building Information Modelling Based On Spatial Structure

Nowadays, the information loss in the different stages of the construction industry isbecoming more and more serious, All stages exit some degrees of "information island"phenomenon, the building information modeling technology can effectively solve theinformation loss of transmission. Besides, more and complex modeling of the spatial structureare more and more popular, the conventional two-dimensional design method has beendifficult to meet today’s architectural design requirements, and every span space structures arerelated to the large number of bars, node information, etc., the various stages of informationloss are serious. The BIM technology is an effective solution to solve these problems, So thearticle concludes the following work:(1)By researching BIM technology and its mainstream software, a detailed comparisonof the difference between BIM technology and traditional CAD technology, the advantages ofBIM technology in architectural design are obvious; By the analysis of the BIM softwaresolutions and effectiveness, we can know that the implementation of BIM technology is theonly way of building information.(2)By researching text input way of the finite element software MIDAS and BIMsoftware Revit software, using the program language of Fortran and C#, the article establishesthe space structure BIM to achieve information core data integration, to achieve theconsistency of information in real-time, and bidirectional association between spatial structureBIM solid model and finite element software MIDAS analysis.Through the research, it creates BIM models span space structure quickly,, and obtainsan effective spatial structure BIM information integration on the background of the Stadiumof Shaoxing,,Changchun toll stations and other span space structure.(3)By researching spatial structure parametric modeling applications basing on the theRhino software plug-ins grasshopper, The article creates a Rhino software plug-ingrasshopper modular program; Using the innovation technological of the structureparameterization applied to build the axis topology relationship, And it successfully applied tolarge space structures’ parametric modeling, take the example of Shaoxing stadium structuremodel, and conclude that the advantages of the parameterization design in the spatialstructure’ every stages.
