Research On Parameterized Reinforcement Of Beams Based On REVIT Secondary Development Technology

With digitization in construction industry,the pace of industrialization is getting faster and faster.The rapid popularization of BIM technology in our country speeds up the transformation of this process.In the application of BIM technology,BIM forward design is the front end of the whole industry chain,which provides data support for the integration and optimization of data in the later period.How to accurately and quickly express various information of building components in 3D in the design stage will promote the application of BIM at this stage.For the structural design,BIM component reinforcement layout more use of double turning die,low work efficiency and the precision of reinforcement layout can not meet the requirements of guiding the field construction,for the late application of engineering statistics is out of the question.To solve these problems,this thesis proposes parametric beam reinforcement information from the perspective of BIM forward design,and realizes parametric beam reinforcement in REVIT three-dimensional model through REVIT secondary development function.The main work and achievements of this thesis are as follows:(1)Summarize the information of beam parameterized reinforcement.Reinforcement information can be divided into two kinds.One is the calculation of reinforcement obtained through the soft calculation of structural design;The other is the structural reinforcement of beam members in the atlas and structural design specification.The extracted beam parametric information should envelope the two information,and the structural requirements of the beam member reinforcement are summarized and classified,and the beam member reinforcement anchorage,connection,avoidance and other information are summarized.(2)Through the secondary development function of REVIT software,the parameters of beam member reinforcement are judged by data,and the construction requirements of reinforcement,such as anchorage length and lap length,are processed through C# programming and background calculation.The construction information is directly applied to the 3D model display.In addition,for the position of the steel bar in the member,the avoidance function is added,and the bending of the steel bar can be manually adjusted to achieve the avoidance of the steel bar,and the bending of the steel bar can be accurately expressed in the three-dimensional model.(3)Reinforce a beam and demonstrate the operation process of the entire plugin.Firstly,load the add-on tool so that the REVIT software can run the plugin program;Secondly,input the parameter information of the beam in the form file so that the plug-in program can call these parameters;Thirdly,by clicking the completion button on the form,parameterized reinforcement of the beam can be achieved.
