Abstract: In order to make up for the shortcomings of the structural test course project,combined with the civil engineering independent innovation test course construction,an external prestressed beam experimental device for static and dynamic testing was designed and fabricated.Investigate the influence of the prestress value of the cable on the static and dynamic characteristics of the structure itself.The teaching effect shows that the experimental research to achieve knowledge internalization and migration is an important way to cultivate students' practical and innovative abilities.
