Teaching Reform of Advanced Steel Structure Course Based on Accident Cases -Taking the Joint Design as an Example

The construction measures of steel structure joints have an important impact on the overall steel structure, the safety of the joint itself and the seismic performance of the structure. In the teaching of the node chapter of Advanced Steel Structure Course for undergraduates majoring in civil engineering, the focus is on teaching the calculation and design method of nodes, and only introductory explanations are given for the construction measures of nodes, and the students' learning effect is not satisfactory. This paper analyzed the current situation of teaching in the chapter of steel structure joints. Based on three engineering accident cases caused by improper joint construction measures, a case teaching idea was proposed. On this basis, the critical issues of teaching in this chapter and the application of cases were investigated. This paper aims to provide some reference opinions for the teaching reform of engineering-related courses, and to provide reference for the construction of practical teaching based on improving students' learning interest and autonomous learning ability.
