Abstract: Based on the current teaching status of structural mechanics for undergraduates of civil engineering. It was specially noted that geometric constructional analyses is too abstract. A solution was proposed based on real objects after thorough review of overseas practice. That can be seen as a kind of teaching models to simulate simplified geometric constructional system. The significance of real objects was discussed. Besides this, components, typical usage and demonstration were also described. The results indicated that they have superior benefits for lecturing structure mechanics. This can well reflect the fundamental significance of the subject in civil engineering courses. The traditional teaching together with innovation exploration, simplified illustrations and real objects are critical to the course.
