With the rapid development of online and blended courses in recent years, such as MOOC, online course, flipped classroom, etc, the informatization and digitization of teaching has become a key research project in many universities. In this sense, digital teaching resources are the basis on which digital and informatized teaching is carried out; the teaching content varies according to different disciplines and courses. Taking the course Building Steel Structure as an example, this paper puts forward a digital teaching resource construction framework based on BIM technology:Textbook-PPT-Model-Animation, that is, the construction of digital resources is completed on the basis of textbooks, with PPT as the carrier, and three-dimensional model and animation as the focus. Within this framework, different sections are logically interlinked and the span of knowledge points are gradually expanded. Accordingly, the application of digital teaching resources is expected to effectively improve students' learning quality, enthusiasm, and independent learning ability in the whole process.
