With the establishment of 2008 Beijing Olympic Gymnasiums and 2010 Shanghai EXPO Pavilions, new types of long span spatial structures appear rapidly. Engineering projects should be introduced in the process of teaching steel structure design. Latest research and engineering cases should be presented by modern teaching methods, which can enhance the ability of practice and cognizance for students. In the teaching process, as-constructed drawing and working drawing of complex steel structures can be introduced to students in detail to enhance their interests and enthusiasm. Practice shows that initiative of students was increased and favorable teaching effects were achieved.
