Development And Research Of Steel Structure Node Design Software Based On BIM

The emergence of BIM technology has promoted the development process of informatization and digitization in the construction industry,and its technical application in various stages of planning,design,construction and operation and maintenance has become increasingly mature.At the same time,applying BIM technology to steel structure buildings is an important technical means to realize the industrialization of construction industry.However,the BIM steel structure design software currently used in China can not fully parameterize and forward design the important connection nodes in steel structure,which results in prolonging the construction period,reducing the work efficiency,increasing the project cost and other problems.Therefore,the function of BIM software needs to be continuously improved.In response to the above problems,the research of this article is based on the second development technology of BIM mainstream modeling software Revit,based on the theoretical research of steel structure-related theoretical research,and focused on the development of steel structure node design software to complete the following research:(1)Based on Revit secondary development technology,the development environment configuration and technical basic research were conducted to analyze the specific application of MVVM design mode to the design software development of steel structure nodes.(2)By constructing the standardization family library of steel structure nodes and using the parameter driven family model,in-depth analysis of the creation process and method of each component in the nodes is carried out,which provides a theoretical basis for the subsequent expansion of more abundant steel structure node types and improves the expansibility and maintainability of the program.Then,a custom steel structure node model is generated and the corresponding node details are derived.It lays a foundation for the development of node computing function.(3)Based on the design specifications of the steel structure node,the design theory and calculation method of software computing functions were studied,and the steel structure node bearing capacity calculation module was developed.By entering the project information,internal force parameters,and material parameters,the program can quickly implement the node carrier capacity of the four types of nodes,and then introduce the calculation process and results data into the calculation template through programming,automatically generate the calculation book of the node instance,save designer pairs The computing book is organized and modified and compiled the typesetting time to improve work efficiency.(4)Based on the above studies,taking a certain project as an example,the parameterization of steel structure nodes and the node computing function have been applied to verify the practicality of the program.By comparative analysis,it has confirmed the advantages of simple and easy operation and comprehensive functions.At the same time,the three-dimensional modeling efficiency of the steel structure is improved,and the node parameterization modeling and calculation are realized.It is a positive exploration of the positive design of the steel structure engineering.
