【Abstract】 To develop high-rise steel structural building information modeling(BIM) software with Chinese independent intellectual property right and fully apply the BIM concept,technical characteristics of BIM are put forward.A high-rise steel structure software system based on the BIM concept is developed with ObjectARX technology and AutoCAD graphics platform.Data interface between three-dimensional solid database and each stage of building lifecycle period are realized.The software system is then applied in Shanghai Center Project.The design functions of a high-rise structure such as finite element calculation,code checking and so on are accomplished and structural models from some general finite element software can be read in.Assembly of the three-dimensional solid model is then performed based on the design results.Data structures of joints are organized,and the parameter sculpts and edit technology of complicated steel joints are achieved.Construction data management including material information and cost information can be displayed and queried totally based on three-dimensional model.The real-time association and consistency among construction drawing,processing drawing and three-dimensional model is fulfilled.Application of Shanghai Center Project shows that the BIM software system can realize the concept of BIM and help the development of information process in Chinese construction industry.更多还原
