In the process of teaching and learning of the basic principle of steel structure course, deep computing systems theory and complex formulas result in much difficulty in learning and mastering the course. Most theories and formulas of the basic principle of steel structure are derived from mechanics of materials, therefore, in the teaching and learning process of steel basic principles, the use of the basic principles of mechanics of materials to guide and inspire the students is a way to improve the quality of teaching the basic principles of steel.
