BIM(Building information modeling) in the AE industry, which is a collaborative work platform based on unique database, a new work method and a new management way of project construction, can improve work efficiency in every stage of AE industry greatly. BIM will be widely adopted because of its great potential, and will lead the construction industry to a new era-the era of building information. However, in AE companies, BIM has been hampered by some problems in its application: do not know how to use BIM to make the design process more effective, how to manage the whole design process if use BIM, more specifically, there is no clear and practical BIM design workflow and method. In this paper, we use the BIM software Revit to carry out the real building structure design process, and discuss the specific BIM based design workflow. First, it shows the whole design process from the establishment of the model to the structural analysis. Finally, this paper summarizes the existing problems in the whole design process, and obtains a BIM based structure design method, at the same time, the problems encountered in the design process are discussed, and some possible solutions and suggestions are put forward.
