基于工业基础类标准的钢结构BIM全数据交互技术OA北大核心CSTPCD

This paper develops a complete data-exchange technology based on IFC standard for various types of steel structures.On the one hand,the complete geometric information and additional attributes of the steel structure model can be derived,so that the universal construction BIM software can parse the model and edit the parameterized components.On the other hand,the complete information can be imported to mainstream detailing design software for steel structures named Tekla,then structure model can be regenerated based on these obtained information,from which the secondary edit as well as the construction drawing can be achieved.Verified by engineering Applications,this technology enhances the integrity of information transfer and the quality of model transformation when applied to BIM data-exchange of steel structure,avoiding repeated modeling in different design stages and improving design efficiency greatly.
