Three issues exist in the teaching process of building structure concept design course, which are lack of the connection between teaching knowledge points, lack of students' ability to use structural concepts, and ignoring new building technology innovations. This paper focuses on some beneficial attempts to address these problems, which includes teaching case base construction and case teaching practice of building structure concept design course. In the teaching case base, engineering design and accident cases collected are relative to key points and difficulties of knowledge refined. Through introducing case teaching into theoretical teaching, the connections between teaching knowledge points and between theoretical teaching and engineering practice are established, and the development of new building structures is grasped.
