Research And Development Of Standard Parts Design System Of Steel Structure Based On Object-Oriented Technique

The steel structure is getting more and more application because of its excellence, such as light weight, short time limit for a project, the environment of protect. The steel structure CAD software can instruct the analysis and designing of steel structure , making the detail drawing of construction. It can reduce the burden of an engineer, improve the efficiency of designing. Developing and applying the steel structure energetically is significant to promoting the modernization of architectural vocation of our country.According to the characteristic of the steel structure design, it is absorbed advantages of internal and abroad steel structure CAD software and analyzed the system with object-oriented system analysis method in the system. It is concluded the characteristic of material object of node in the system. It is established the object module of standard parts designing system of steel structure with abstracting the complicated standard parts of steel structure in the format of class in the system. At the same time based on the module the database module of whole standard parts is established using diagnostic technique of parts' s parameter.It is realized that the application of secondarily 3D standard parts library of steel structure based on Solidworks software by using COM technology in the standard parts design system of steel structure. It is realized that the function of entity sculpt of the node of steel structure and making the detail drawing in the system. It is realized that the main interface of system with plug-in technique and the communication with users. It is visited that the Access database with ADO technique and realized that the dada of storage, modification and refresh in real time. Jt is realized that the saving of node' s data and creating the able of materials.The standard parts design system of steel structure is designed with the C++ language, under object-oriented program circumstance (VC++). It is realized that the designing of node of steel structure on standard shape in the system. It can help us improving the efficiency of the node' s designing. It can advance the development and application of more and more steel structure CAD software.
