According to requirements of building steel structure design course for civil engineering majors, animation courseware for factorial steel structures was developed. The research and study of the courseware was based on the actual manufacturing and installation of steel structures. The full arrangement of single layer factorial steel structure was animated in detail and the animation was emphasized on the assembly and formation for typical joints in steel structures. With the development and application of the courseware, the design process of steel structures was lively showed and the teaching concept of “taking teachers as leaders and students as the main body” has been realized in specialized courses.
